TS-850SAT stage 1 repair _almost_ done






nearly done on the CAR board.   Unfortunately the traces were in pretty bad condition under one of the cap's with the copper disintegrating during light cleaning.

I've lacquered over all the exposed copper and replaced the 10uF cap's with appropriate values.   Unfortunately I'm missing the 47uF cap needed to complete the job and test the board... - Full Post
