The spider pots are a treasure hunt. I was searching for them just a few years ago as I had a DynaBass that had some pretty wonky spider pots. I also wanted to maybe get another set to have on hand. Found some, but not at the values/tapers/size I was looking for. The one I found were 16mm vs the 25mm I was replacing. There would have to be a little modding to make those smaller pots (with slightly different spider leg splay) to work on the stock circuit board.It's mostly items like spider pots and that double diode Peavey used for the overheat protection circuit. They're probably available, I would just have to search. 20 years ago, it was easy to call the Peavey parts department and get everything you needed.
I gave up looking for new replacements. I eventually decided to take a calculated risk and rebuild. Pulled them apart, found a similar value/taper CTS wafer from a donor pot and rebuilt one. I was able to just take the other 3 apart, clean, relube and put back together a little more tightly. They, as a whole, ended up performing reasonably, not perfectly, but good enough for RnR. Another vote for CTS pots that are reasonably serviceable!
