The Post I didn't want to make....

2016-02-07 by jw_dewdney@yahoo.com

Well I got the Jorgensen KLM 367 transplanted back into the P6 and thought I'd try to take it on a test run. I even went so far as to get all the VR pots back into the ballpark (compared to measured values from the old board)... I've been SO unbelievably cautious with this build (even did every solder joint under a stereo microscope) - I was kind of half hoping it would work straight out of the gate.

But NO.

what came through the headphone jack sounded healthy at least (the usual P6 hash noise) - but EVERY LIGHT on the front panel was lit up and there was NOTHING I could do about it (no matter how much button pushing etc). Does ANYONE have any idea what the problem could be (wrong DC offset from VR5?) ... grounding problems? Has anyone ever experienced this before from a Jorgensen board build? (yeah I did correct for the bugs in the board etc) - and no - i'm not getting any audio on key depresses.

This particular P5 showed no such symptoms before putting the board in... just the usually flakey KLM367 problems...

thanks in advance
