This Proj set is really giving me fits. Came in dead, found pulling P1903
Audio plug restored normal operation. I replaced both audio out IC`s, no
help. found it still shuts down with both U1901 & U1902 removed. Measured
both the + & - voltages at the plug & both are running around 18V. With the
ic`s both out I can resolder the pins 2-3 & 6-7 that have been disconnected
to get the set to power up 7 set will continue to run with normal voltages
on the + & - supplies, but when I shut it off it will not restart. Have
checked caps in the circuit & find no problem. What has anyone else found
bad in this audio circuit? or any info to narrow down my problem would be
appreciated. thanks Larry
