I have a set of Harmon Kardon hk395 speakers, that the volume pot is going out on. Wondering if someone would know where to find one? Volume pot controls both speaker channels as well as is the on/off switch. The pot is marked 3B50K w/ a d shaft and has 8 pins.
Found similar, but most don't incorporate the switch. Thanks.
