Hi, I recently came into possession of an '85 4104 combo which sounds amazing, but it has one issue - the bass pot has no detents. It's not unusable like this, and I just set it where it sounds good anyway, but I'm thinking I might want to replace it, if only for completeness sake. This is the horizontal input model, with chassis mounted pots and jacks. Does anyone know what the bass pot value is, and where's a good source for one? Thanks, Sean
1M. I got a whole set from ebay. Don't remember the exact store. Do a little searching, you'll find one. Good Luck!!
Are they 1m audio or linear? Do I need to search anything specific for the fact that they're PCB mounted? Thanks!
With detent, do yu mean a spot in the pots travel where it clicks into place? Like maybe in the center position?
Hi Ricky, No, I mean like, it has no 0 or 10. It spins around freely. Yet, it does affect frequency, so I think it's just the stop or whatever that has broken.
Oh, I see. Yeah, that would be annoying for sure. Yeah, you would want to go with a 1MEG audio or LOG. And then if it is PCB mounted, yeah you need that type. BUT . . I have used standard type or non PCB mount where it had a PCB mount originally and just ran small lengths of wire from the lugs to the PCB. I had a quality pot on hand and that is why I did it that way
