I acquired a Peavey commercial rack mount equalizer from the mid to late
80s. It appears to work well, aside from two problems. First, the AC power switch was bad. I temporarily just jumped it, till I can find something to fit the hole. Second, one of the slide potentiometers is broken off, and it happens to be the main (GAIN) one for the left channel. I was able to lift it with a thin tool, to it's max position, but I want to replace it.I found an online schematic. It's a 50K pot, and it says "all pots are linear". But on the schematic it says 50K "s". I'm assuming the "s" means SLIDE. Is that correct? (If not, what does it mean?)
I have never replaced a slider pot. To obtain a replacement, are they all the same size and pinout? Or do I need to go by any specs? Since it solders directly to the PC board, it has to pretty much be identical.
I plan to first contact Peavey and see if they have this part, along with it's knob, but considering the age of this device, I suspect they wont. So, if they dont have it, how do I match it up? (I'll be buying this online, so I have to make sure I get the right part).
If it matters, this is a Peavey EQ 215 equalizer.
Thanks
