Hi all there,

a friend of mine who have a P6 alredy repaired by me, called me describing strange behaviours.

The P6 suffered a wery little leakage on a minimum area.
Its major issues came from a big touring life, this P6 was really smashed to bits the first time i put hands on it.
No screws, big deformations on chassis due to huge hits suffered, one of them slammed the klm367' connector cn10 which needed a complete replacement with standard row connector, more than this lots of potentiometers were reduced to mere debris, broken patch buttons and so on.
I've fixed it giving him a new life.

Now after few months, the p6 is suffering these issues:
- 4' 8' 16' pot is partially working, it drives from 4' to 8', then once turned to 16', it goes back to 4'.
- EG ADSR functions work only if "phase" is selected on effect switch, on other selections it drive to "gate" mode.
- WAVEFORM switch remains stuck to pwm at any selection.
-  if A1 A2 B1 B2 patches are selected, the led lights up in non proper way, ligthing both A-B and 1-2 buttons., other patches work flawless.

Checked the traces of newrow connector, everything seems fine.

Started the reset calibration with dummy 56k, ok.
Then the a/d, i cannot get the 1 and 8 leds on only.
I've tried a lot on Vr6 Vr7 but the best result is 1-2-8 leds on, but it's not a big deal.

Any suggestions?
Thank you.
