Thank you Paul! I’ve been an electronics technician for years and I still learned a lot.

2025-01-04 05:21:13 +0000 UTCI noticed a lot of capacitors, even electrolytics, had wire sleeving over the leads, others did not. How do I know which leads need sleeving and which don't? Do AA5 radios need sleeving in areas as well? Thanks in advance to any answers

I have never seen this, only a separate winding for the main transformer that runs all of the heater fillaments.

2024-03-31 03:08:11 +0000 UTCWouldn't the hum be reduced in the signal tracer by adding a grounded cord set instead of the 2 wire one? I also noted the use of copper braid ground leads near the RF amplifier tube.
