Swapped out the output caps with some other caps to do some comparing and now I have knocked out the one channel ( red - positive) have looked with strong lite and magnifying glass, can't find anything touching, this one has got me stumped!!!!!  Any hints or places to start or measurements I can take to track down what the hell I've done would be most helpful!!!  Of note, both channels were working perfectly before I meddled.................

I guess the first step is to put your old cap back.  IIRC the output cap is between a terminal and the output RCA Jack center conductor.  At least I think.  So let's eliminate the cap.  Only change the one that is giving you trouble.  Test.  There could be a break in the solid wire on the new cap.

I suspected as much.  I would guess you have a loose connection.  Look for solder joints from the input RCA jack forward.  If you need it I will post a list of terminals to check. 

If you have the C4S then first check if all the LEDs are lighted.

Man, do I feel like a dolt!!!  I had blobbed on a whack of solder and effectively shorted the RCA jack, fixed now and gonna give a listen to these Obbligatos Smiley
