Have a technical question that maybe someone has confronted and can help me with. Or, maybe the electricians amongst us can maybe help me out. Bought a used Porter Cable PC 160 JT Benchtop 6" Jointer some time back, broke the speed control knob off on the way home from the auction sale. Other goodies fell over in the back of the car, and hit the knob, Chinese junk, it's a plastic shaft on the potentiometer behind the knob. Was going to replace the Speed Control Module, it's a simple little board, nothing to it, until I looked it up. Morons want more than I paid for the machine for that little bitty board, in fact they want half the price of the machine NEW for a replacement board... IF you can find it. Most places it is listed as no longer available from the manufacture. Which this is hard to believe since Porter Cable still sells it, AND... Delta sold the same identical jointer under their brand name. Same model number, same parts list, same part numbers, whole works... So it's not like there isn't a few of them out there. And, I'm not paying $300 for a board the size of a credit card, with $5 worth of parts on it. I can buy a sack full of the needed potentiometer on Amazon for $10, 3 pins to desolder and resolder. It's a simple enough fix, but no specs on the potentiometer, so I'm not sure what I need there. And, schematics on the control module to help out. But, then I started looking to see if maybe I could buy the speed control module on E-Bay, and I can buy speed control modules complete for anything from $2 - $15 dependent upon application on E-Bay, IF I knew the specs on the board. Before I spend all the time to dig up all the necessary specs, to sort this out, has anyone here replaced one of these speed control modules with after market, and if you have would you happen to have a part number?
