Rare 1973 Heathkit BUILD! Pt.4
Added 2019-01-02 04:07:27 +0000 UTCIn part four of my idanno how many parts series of the nostalgia Heathkit IT-12 build I set out to get the rest of the sub assemblies done and find that I have to come up with some of my own solutions. All part of the Heathkit experience. I talk about Magic Eye Tubes and some other stuff too. Enjoy!

I know, it was an "I would" not "you should." For me after using silicone microphone and probe wire, I can't stand fighting other kinds of wire.

2019-01-04 16:38:14 +0000 UTCI think I would use a nice silicone wire for that probe, can't stand stiff probe wires.

2019-01-03 22:11:22 +0000 UTCFairly sure the line on the 100n film cap indicates the outside foil layer. In some cases the orientation of this can influence hum pickup.

2019-01-02 18:29:36 +0000 UTCThat probe looks complicated...
2019-01-02 14:49:45 +0000 UTCAlso "that" capacitor is possibly marking the outside foil, not the polarity...... It's just to foil you.

2019-01-02 05:26:08 +0000 UTCThose magic eye tubes were not controlled in the alignment of the "eye" relative to the base. Not Heathkit's slip, we have to mutter at RCA and other tube/valve manufacturers. They were fabricobling these tubes to welders' tolerances,+/- 1 degree. Sadly welders' degrees go two to the revolution, much as their thous come at 3 to the inch. ;-)
