    Phase Linear 300 sII Trimpots

    Are trimpots pretty much equal other than values and physical dimensions etc? I have recapped and replaced all semiconductors in the unit, along with all resistors but output relays would unlock after about 30 seconds after power on and would not lock up again until the capacitors had drained...

    Replacement 2285B pots

    I’m replacing the main amp adjustment pots and thought I would share how I did it. I took a page form a picture I saw where the tech made a nice etched board to mount a new trimpot on it. In my case, I used some perf board which is not as pretty but worked pretty well. I also found that the...

    I'm replacing the trimpots in a vintage (1970's) receiver and I've ordered standard Bourns trimmer resistors, but the new pots have 5mm lead spacing whereas the old ones have 7mm or 7.5mm, so the PCB has the wider-spaced holes. What is the best way to deal with this cleanly and reliably? 1. I...
