Problem with shifting volume: Zenith K-731

[Nick_the_'Nole]

I have a similar problem on my Zenith, C725 or something, no model number tag on it... Anyway, I checked the resistors and everything seems to be reasonably close to rated value. Some of 'em have drifted to about 7% out, but they were tolerant to 10% anyway, no? Of course, I wasn't gonna check 'em hot, since I've had bad experiences doing such things. I *did* however, find some extremely leaky electrolytics while I was poking around. I haven't replaced them yet to know for sure if they're the entire problem, but you didn't mention whether yours had been recapped yet, so could it be that simple?

I really want it to be that simple, 'cause I don't wanna track down bad resistors again...
