Hello to the group! In the process of repairing one of these and the schematics list the part nos. and values of the pots for volume and balance but the numbers don't seem to cross to anything I can use. I know the volume is an ALPS but the owner peeled the label off the balance control to lube the wipers so I can't ID it at all. The ALPS number doesn't cross to any current production that comes close, and I am lost on the balance control. So rather than hunting for the right shaft style and length, and the mounting hole size, can anyone tell me what they might have used for this replacement? Would save me a bit of huntng for the correct physical attributes. Thanks, and Cheers!!
I have a PL 4000 Series 2 that needed a volume pot replaced and searched for a step pot like the original and came up short. I ended up using an Alps 100k stereo audio taper 042G and did a retro fit. Converted it to a D shaft(shortened it as well) and it’s working good. Painful process but it works.
