Quad 33 woes
Hi All
I’ve had this 33 for many years. I had refurbed it but the front edge of the filter section pcb had I later discovered had a hairline crack in the board which cut across several traces. As such it was unreliable even after bridging with wire and was put away. Having obtained some new filler epoxy that’s like a powder you fill gaps with and a setting agent that fixes it I thought I’d give it a go. Anyway that seemed to work on the board which is now solid. I rebuilt the bridged traces with solder and continuity is good. Stupidly I also sprayed servisol into the switches and now none of the push switches on the filter side will lock in :0( I’ve blown hot air in to try and dry out the lubricating effects of the servisol but no joy. It’s an early unit 8776. Have I wrecked it? Any way to bridge the switch contacts to permanently set it to 5 or 7 k? At the mo all switches are out so not on cancel or any setting.
Thx
Mike
