Re: Noisy/drifty S-6 head


Hey Roger,

I tried cleaning the edge connector, but that didn't seem to help. So took
the head apart and gave the two pots as well as the board-to-board
connectors some D5 and I gave the pots each a wiggle. The "wobble" is now
gone and I have a rock-steady trace.
However, I clearly need to calibrate the head - not that it didn't already
need calibration. I guess I'll need to hunt for an extender ( - people on
ePray sure are proud of their extenders...

In any case, thanks,

There are two preset pots in the S6 head for gate balance (R30) and 'gain'
(R45), either could be noisy, but a more obvious suspect is the edge
connector from the S6 to the 7S12 since the DC / low frequency feedback
path has to travel through the edge connector.
