TS940 AVR Board

Mani Page     Page Up


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.



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.
