Replacement parts for Proco Turbo Rat

Hi all, I'm looking to replace the foot switch and one of the pots in my Turbo Rat. My problem however, is that I can't find anywhere that sells the original parts needed to replace the broken ones.

If anyone would be so kind as to direct me to somewhere I can buy the parts, or otherwise compatible replacements (I'm not too good with the circuitry and electricity thingys, just handy with a soldering iron), it would be much appreciated.

Also, if anyone has video of the disassembling of a turbo rat, it would be extremely helpful - I'm fearful I'll break the damn thing's circuit board trying to prize off a pot.

PS. If it helps, my Turbo Rat is an older model: RT - 158229 (according to the back).

Thank you for any help!

A100k pot and either dpdt or 3pdt fs. Small Bear, Mammoth, Pedal Parts Plus.

You won't find "original parts" unless you harvest them from another unit.

Whats the difference between the dpdt and the 3pdt foot switch?

DPDT: double pole double throw, 6 lugs
3PDT: triple pole double throw, 9 lugs

I don't know about the newer ones, but the vintage RATS used a DPDT footswitch, and either didn't have an LED indicator (early versions) or used a "millenium bypass" circuit to activate the LED but still allow true bypass.

I recommend SmallBear electronics, I've had great service from them and they ship overseas.

They don't have the footswitch listed, but I know they probably carry one that will work. To disassmeble your RAT: Remove the control knobs, remove the nuts and washers on the control shafts. Remove the nut from the control switch and DC input jack. Here's where my memory gets fuzzy, but I think you need to unscrew the bushings around the input and output jacks. The circuit card with the pots and switch mounted to it should come out easily.
