Its not tubes, but I have a pat-4 preamp with a bad treble pot. The owners/assembly manual says its a 40k pot, but alls I can find here locally is a 50k pot. Is there any problem with this, or would it be better just to put a resistor in place, alls I want to do is center it to be flat. but the pot is all screwed up and I can't get good contacts.
thanks

Also forgot to say that I just found this forum and I appreciate reading about good old audio gear.
thanks

Hey, Duder, welcome to the forum! Take up Bob on the offer. That "40K pot" in the PAT-4 is not just any ordinary pot, but a special one designed by Dynaco to take the treble tone control out of circuit when it's in the center position. Yes, there IS a way to modify a standard pot to work but this offer is too good to refuse!

Bob just wanted to say that I did receive that pot last Friday, haven't got the chance to put it in yet but hopefully in the next week or so. once again thanks.
