TS940 AVR Board
While tuning up the unit for use and getting the microphone squared away, Bob and I smelled hot electrons. I pulled the top cover and with a Ray-Tek gun discovered a filter capacitor on the AVR board that was starting to short. This doesn't surprise me on a 20 year old rig. I pulled the AVR and DC-DC boards to re-cap them.
Before...
Here's the AVR board after the re-cap. Purple sharpie allowed me to keep track of what was and wasn't done during the replacement.
