i am searching the volume potentiometer for this unit.
250K-B1 ref ACV-134 (VR2)
Can somebody help me
I will check out my spares, but don't think so, from the models you gave.
I checked my spare boards, as well as my loose Pioneer parts, I have gathered over the last 5 years.
I found quite a few balance pots and tone pots, a lot of Quad pots, but no 250K x 2 Volume pots.
I just looked on Ebay for you and didn't see any volume pots, but did see 2 balance pots, one for only $14.
I believe the only difference between the 2 is that the balance pot has that detent usually at the 12 noon position, but shouldn't affect its function as a 250k x 2 potentiometer. You could even get creative and remove the back cover, to disable the detent. The listing refers to it as "ACV-135". I found it by doing a search on SX-737
There is only one problem. Usually balance-potentiometers are linear,but those about volume control are logarithmic.Sometimes(very rarely) balance potentiometer can be logarithmic, but you have to make sure in this.
"B"-logarithmic,"A"-linear.You need "B".As you write-250K-B1...
The potentiometers which are you looking for have extra - fourth terminal for loudness switch.Balance potentiometer no such terminal.
