Ok, Thanks for reading my post.
I have a Taylor 68 A/M RF and AF sig gen (valve) off eBay, cheap.
Low volume on AF and low output RF signal. Tracked it down to the volume pot obviously.
100k lin with 2 pole switch on/off on the back. Gone to 380k with most of the track gone.
The worry I have is, it says nothing about power disipation of the track. It's a fairly big pot at 40mm dia with a metal back, bakelite front and patent number 439028. I don't want to put a standard modern one in just to have it go bang on me or cause more damage .
If you have any ideas or a circuit diagram that would help a lot.
Thanks
