A List Of Verified Parts To Stock Up On.
Added 2017-09-01 15:27:22 +0000 UTCI have completed some component testing, and found these parts to be "really good." I will be using these parts in many future builds. If you're following along with my design,restoration and repair videos, it would be beneficial to have the same components. As these videos progress, I will verify more components, and share my results with you.

Is there an update to this list....it is 8 years old....
Timothy M Tapio
2025-09-03 00:39:05 +0000 UTCMaybe I’m having a senior moment here but need to clear this up. Anyone out there please confirm…. When holding the capacitor, and transferring signal to its most outer plate (shell), than the signal lead to the oscilloscope being larger would be that side to be grounded, or come from the plate of a tube, Banded side. Right?
Michael in Florida
2025-07-25 00:05:36 +0000 UTCYour reference to the 'verified parts list' implies there is a list of other parts beyond capacitors. If there is, could you location to find it? Thanks
Clifton Schlicher
2024-01-18 17:53:04 +0000 UTCAn update regarding this list you might want to make — Rubycon 450TXW47MEFC16X25 is not a current number. The current part would appear to be 450TXW47MEFR16X25. (Note the R in place of the C.) Rubycon also has a newer series which includes 450BXW47MEFR16X25 which has twice the ripple current rating for just a few pennies more per cap. The other specs look the same. Also, Jay, please check this component in your mouser cart. You have a PK one there, and that is not the same animal.

2022-03-31 14:06:40 +0000 UTCAnother awesome video! I am going to get stocked up on these parts for the restorations and repairs bench. Thank you very much.
Jared Kusner
2021-12-31 15:39:37 +0000 UTCI've seen on lower value (like .015 uF) polypropylene capacitors have very little difference between the foil and "non foil" ends. Too little to tell. MUCH more obvious with say .022 uF and larger caps. Also, I can't find any good answer to if you have an audio amp with a capacitor in series with the input connector which way the foil side should go. I assume that the input is the lower impedance, but wouldn't the foil out pick up noise also? Great video and tool also.
Ryan Dunbar W1RMD
2021-11-06 15:28:14 +0000 UTCI just ordered 15 of each on the list. Mouser had them all in stock and the cheapest price. When they get here I have a Zenith as my first tube restore project.
Halfhorse
2021-08-31 18:39:36 +0000 UTCThe LED is inverted to the way we usually think. It is showing "ground" not probe. If the foil is 'grounded' it shows a lower signal on the scope because the noise is going to scope ground. If the internals are "grounded" (it's LED is lit) then the probe wire is connected to the outer foil and more noise is shown. If he had wired it up so the LED shows the probe connection, then Higher signal= outside foil.
Sprocket Tinkerwind
2021-08-18 03:34:44 +0000 UTCGlenn, I think your reasoning is correct (I am new to this, so take it with a grain of salt). The outside foil is connected to the center lead of the coax cable when the light is OFF om that side. If the hum is HIGH on that side, it means that this side is the outer foil. Looks like this approach is inverted where we look at a LOW hum on the side that with the led ON (tied to ground). I may not understand this correctly, but I would have used the ON state for the center and hum HIGH as indicator, essentially inverting the light signal and the scope reading. Does that make sense or am I missing something here?
Daniel
2021-06-12 05:00:27 +0000 UTCI have watched this a few times. I must be having a senior moment. By holding the capacitor, inducing noise to the outside foil, wouldn't the larger noise shown on the oscilloscope be the outside foil? In my mind, the inside foil (being protected from the outside foil) would show the smallest signal.
Glenn Hooper
2021-04-05 18:59:13 +0000 UTCQuestion about a resistor assortment. Seems like 1/2 watt carbons are the rage in old sets. Can I buy a large 1/2 watt Chinese set off AMAZON ? Are they any good ? They are not carbons I guess, But does that matter in circuits, As carbons vary over time ?
Robert McDermott
2021-03-03 05:55:47 +0000 UTCLooks like you have bought all the WP424QR51WT/D-AMT (blue led) in the world :) any alternative?
Murat ERAYDIN
2020-12-16 10:26:00 +0000 UTCShane, it looks like RG-316
Jimmy Moore
2020-10-09 05:10:10 +0000 UTCPaul, do you mind sharing the info on that coax cable? It looks great, I see you've used it in a lot of builds. Can't find the info on here. Thank you,
Shane
2020-06-05 17:15:32 +0000 UTCno... because the 2 channels share a ground....
Allen Haswell
2020-01-17 22:54:21 +0000 UTCIf you had a 2 channel scope could you hook the probes with one set opposite and determine which set was on the foil?
Brian Mathews
2020-01-15 03:31:19 +0000 UTCIf you have to choose between a lower or higher capacitance for replacement parts, is it better to go one way or the other?
Rick kennard
2019-11-06 12:40:19 +0000 UTCWow! I can't tell which of those two Vishay capacitors is real and which one is printed on the paper! Haha
Bruce Dow
2019-04-19 22:59:35 +0000 UTCHi Roger. Those Solen capacitors are good. I haven't tested any on the forecast position of my newer cap tester, but I imagine they would pass.
Mr Carlson's Lab
2018-07-24 00:34:38 +0000 UTCMr. Carlson thank you for the capacitor list. my Mouser order just arrived today. i found some on ebay the brand is "Solon" from France. I was wondering if you have ever heard of or tested them before? they have some with good values .01uf @ 1000vdc and they are Metalized Polypropylene. here is a screenshot of them...<a href="http://prntscr.com/ka14vz" rel="nofollow noopener" target="_blank">http://prntscr.com/ka14vz</a> have you seen them or tested in the past? thanks for your time.
ROGER BRUMLEY
2018-07-23 19:09:24 +0000 UTCI have noticed a number of times that you have "gobs" of components, some just bulk, some tape and reel type, etc. To say I have been jealous would be an understatement. Rather than hang on to that, I wonder if you could provide a source where these items could be purchased in bulk at a "poor man's" price?
Wayne Thompson
2018-06-18 06:12:09 +0000 UTCHere's a good video showing a similar way to test for this using an audio in to your computer. The guy made his own box to switch back and forth between tip and ground. You can do this by simply downloading Audacity (Windows/Mac) and creating the necessary audio input cable for your audio card. BTW, I take no responsibility if this frys your sound card. Here's the video demonstrating how it works. <a href="https://www.youtube.com/watch?v=J_myAR9TO0g" rel="nofollow noopener" target="_blank">https://www.youtube.com/watch?v=J_myAR9TO0g</a>

Mr Carlson's Lab
2018-02-10 19:45:09 +0000 UTCAren't the Illinois polyester capacitors virtually identical to classic Mallorys? Also, instead of (or in addition to) the dot, I'd crimp the outer foil lead to build in a little thermal stress relief.
Peter Sage
2018-02-10 19:06:45 +0000 UTCIs there an easy way of detecting the outfoilend without an oscilloscope?

2018-02-02 07:00:54 +0000 UTCThanks for your input Mike!
Mr Carlson's Lab
2018-01-08 12:23:47 +0000 UTCThank you Jordan for the list it's a real timesaver.Mr. Carlson I was thinking something that would really be helpful to people like myself were just getting started in electronics.A list of commonly used components. To build up a supply so when not searching for each project. Not suggesting you source them. Just a list for us to hunt down. That's part of the learning process. Mike R
Mike R
2018-01-07 19:56:24 +0000 UTCI think so, but here's the thing, IC is a great name and you know the facility is good.
Mr Carlson's Lab
2017-12-28 09:16:27 +0000 UTCI ordered 10 each from the list. Is everything made in China now?
scott palmer
2017-12-27 21:22:16 +0000 UTCThanks for taking the time Jordan.
Mr Carlson's Lab
2017-11-16 07:48:33 +0000 UTCI created a Shopping list on Mouser.com with all these parts included. Go to <a href="https://www.mouser.com/Tools/projectcartsharing.aspx" rel="nofollow noopener" target="_blank">https://www.mouser.com/Tools/projectcartsharing.aspx</a> and search for this identifier "5a721a8734" and anyone can access it or buy it. 10 0f each item is about $116.16 U.S. plus shipping, 100 of each is about $900 or so.

2017-11-16 06:04:26 +0000 UTCHi Steve. I made some "Break out" boards for smaller components. Basically just make some small PCB's with a single component pad arrangement and add some lead out wires.
Mr Carlson's Lab
2017-09-24 22:42:41 +0000 UTCI saw on your ft1000 repair video where you had a surface mount transistor on a breadboard, where did that transistor assembly come from?
Steve Jones
2017-09-24 19:38:00 +0000 UTCThis cap 566KXM050M , I would have to ordered 3000 of them but digikey has it in 493-1897-ND Nichicon cap, are they any good?
Larry { N7LUF }
2017-09-22 23:37:59 +0000 UTCI want to recap a Yeasu FT-736 power supply and part list I have is for Panasonic Industrial Devices and from digikey.

Mr Carlson's Lab
2017-09-22 09:10:02 +0000 UTCAm I hearing that "<a href="http://www.digikey.com" rel="nofollow noopener" target="_blank">http://www.digikey.com</a>" is the only place one should buy parts from safely?

2017-09-16 05:31:12 +0000 UTCThanks Paul I will try that. I found a site in Canada justradios for the capacitors.
Rodney Garrett
2017-09-12 02:30:14 +0000 UTCHi Rodney. The community section is a great place to ask questions, just start your own post... you can add pictures too! The resistor is very close to 10 Ohms. If you have a way to measure resistors with good accuracy, test a whole bunch of 10 Ohm resistors, your bound to find one that measures 9.7 Ohms.
Mr Carlson's Lab
2017-09-12 01:32:44 +0000 UTCNot sure if this is the correct area to post a question like this. Let me know if I need to move it. Thanks
Rodney Garrett
2017-09-12 01:18:40 +0000 UTCI am trying to rebuild a EICO model 232 VTVM. I want to change the capacitors and I know that one precission resistor is burnt out. It's value is 9.7 ohm 1/2 watt and 1% .Am I going to be able to find a replacement? Some of the caps I need I looked for on Digikey but they didn't have them. Any Help?

2017-09-12 01:14:09 +0000 UTCMade my order with DigiKey. Seems they were out of the .1's. I'll get 'em from Old Radio's.

2017-09-05 23:15:05 +0000 UTCGet yourself a Digikey and Mouser account, in the UK, provided you spend more than £33 before vat shipping is free, there are also no customs fees or duty to pay as they take care of that their end. They are remakably quick too, I placed my last order 21.40 on a Monday night and it was delivered at 12.15 on the Wednesday.
Eddie Bray
2017-09-04 07:01:23 +0000 UTCIllinois caps are trickier to get from UK supplier's and can incur an extra delivery charge of £15 from Farnell as they come from the depot in France. I use these - <a href="http://uk.farnell.com/vishay/mkt1813310635g/cap-film-pet-10nf-630v-axial/dp/1166871" rel="nofollow noopener" target="_blank">http://uk.farnell.com/vishay/mkt1813310635g/cap-film-pet-10nf-630v-axial/dp/1166871</a> made by Vishay. Ero caps are decent too. I find the results when testing for the outside foil a bit ambiguous sometimes, even with the scope on 1mV/div.
Diabolical Artificer
2017-09-03 07:10:58 +0000 UTCI do agree.
Mr Carlson's Lab
2017-09-03 04:31:34 +0000 UTCI actually have some of these yellow tube style Illinois Caps I got from Digikey a while back. The only downside is that they are expensive. Same with Vishay. Excellent video though Paul! Also I'm going to plug Digikey here, it is really the only place that I haven't had counterfeits or cheap crappy components. You will pay full retail for parts though, so it's better to order in bulk if possible.
Dacke
2017-09-02 23:45:54 +0000 UTCThat means that there are two capacitors at 500 microfarad inside the can. Each shape represents a separate capacitor. For example, I have a few cans that have four capacitors inside them, with one terminal marked square, another half circle, another triangle, and the last one is a line. Each one should also have a voltage rating. The can itself is the negative connection.
Dacke
2017-09-02 23:43:04 +0000 UTCPaul, First thanks for all your videos. I have an old car AM radio that I figure no big loss if I screw it up while learning about it. My question is that it has an old aluminum shelled capacitor marked with 500 MFD twice 1 has a triangle and the other has a square. These markings are also next to each post on the bottom of the cap. What do they represent ? Thanks.

Mr Carlson's Lab
2017-09-02 05:19:21 +0000 UTCThe parts you listed are rated at 400+ volts. Are your future builds going to require a high voltage power supply or direct mains supply?

2017-09-02 05:18:55 +0000 UTCThanks Ralf!
Mr Carlson's Lab
2017-09-02 05:18:23 +0000 UTCDefinitely a video there. I could write a book about this.
Mr Carlson's Lab
2017-09-02 05:16:50 +0000 UTCNot to push digikey or anything, but I find they sell good components... (haven't had any counterfeit's yet)
Mr Carlson's Lab
2017-09-02 05:16:06 +0000 UTCHi Dave, that should get you started. Many of the projects that use those capacitors are "spur of the moment" over here. So I never know myself how many caps are needing replacement until I open up the unit. You will find each project is different, and many manufacturers just use caps they got a 'good buy" on. So, one project may use ten .01uF caps, and another may use twenty.
Mr Carlson's Lab
2017-09-02 05:14:30 +0000 UTCHard to say Steven. There are so many counterfeit capacitors on the market today, one has to be pretty careful. Oddly enough, some of the older orange dips get leaky! I really think some of it is just environment, and bad quality control. I would test your orange dip caps for capacitance and leakage. Usually the counterfeits show really low for capacitance, as they skimp on material.
Mr Carlson's Lab
2017-09-02 05:10:21 +0000 UTCThanks for the kind comment Bruce!
Mr Carlson's Lab
2017-09-02 05:05:44 +0000 UTCPaul: I am interested in learning more detail about how you define and determine "really good" for a component such as capacitors and resistors? Are there a set of parameters, tests and minimum specifications that you could share with us, so that we might learn how to judge parts that we already have on hand? Or is the subject sufficiently deep that it would be worth a video? Thanks
Steven Munts
2017-09-02 03:11:45 +0000 UTCIs this for the course, or just for your regular youtube videos. If for course about how many should we buy (to follow along)? I just put quantity 10 for each into digikey (<a href="http://www.digikey.com/short/qc3cbr)" rel="nofollow noopener" target="_blank">http://www.digikey.com/short/qc3cbr)</a> and it's $90. I'm willing to spend the money, just wanted to make sure I didn't get ten 0.47uFs when I really needed twelve .01uFs

2017-09-02 01:44:49 +0000 UTCLooking for the best place in the Toronto area to buy components?
John Fitzgerald
2017-09-02 00:12:00 +0000 UTCI have a question for Paul, but I am also interested in the thoughts of others as well. Paul, are "Orange Drop" capacitors considered as good as the ones you listed? Or does it depend upon the source of the Orange Drop? I have noticed several antique radio restoration parts supply web sites that advertise the Orange Drop capacitors. They generally offer them in a quantity for each of a number of capacitance values. Before I found your YouTube video's, I purchased some from one of these shops. Now I am wondering if I wasted my money and should discard them. Any advice would be appreciated. Thanks

2017-09-01 19:14:58 +0000 UTCPaul, you MIGHT consider opening up a branch of Amazon.com for yourself... just stock the GOOD stuff! We'll all buy whatever you stock... believe it! LOL
Bruce Havourd
2017-09-01 18:45:46 +0000 UTCYou're right Anders this is also a valuable note! I made the mistake and mixed up quality with quantity. Some of the cheap Elko's are already bulging and all of the LM337 I got from the Bay are faulty. Lesson learned :D
Reb Elba
2017-09-01 18:19:26 +0000 UTCVery good advice, many thanks Paul! From my experience I don't get all the parts from stores in my country like Reichelt or Conrad. Mouser or Digi-Key are good alternatives but I have to keep an eye on the shipping cost's :)
Reb Elba
2017-09-01 18:07:47 +0000 UTCAnd one thought that came to me... GUY´S !!!!, please be careful if you browse E-bay, web etc.. especially when it comes to electrolytics, .....good Caps ARE expensive, so it´s always a good practice to choose known brands from the beginning so you dont get bad habbits from the start :-), Have a wonderful day all of you.. /A
Anders "SM7HCE"
2017-09-01 17:28:33 +0000 UTCNice move Paul, i dont want to do any advertising aswell, but i nowdays always use justradios.com´s capacitor kits when restoring any old tube cirquit ... atleast when it comes to Metalized Polypropylene.... i find that they are pretty ok ....one nice thing with them is that the original values are available even if it doesent matter much if a cap is 50 or 47, .... there is quite some tolerance in the old stuff :-):-)
