ok, I've finally got round to wiring up the PT in my '76 Marshall Superbass head. it's the correct part# bought directly from Marshall.
I've checked the wiring many times and planned it all out carefully routing the wires correctly using chassis pictures from another '76 Superbass.
The problem is that I'm getting a vibration on the PT when I touch it. Any ideas what this might be????
btw, I replaced all of the filter caps and the whole bias circuit since it had been bothched in the past. I've ran the amp at bedroom volumes for a hour or so and the PT never got warm so I'm just wondering if I'm being overly cautious.
anyone?
