Little help with 100k lin pot. Please?

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

number 439028.

I would have expected that to be a UK patent, but I couldn't find it here:

Maybe you'll have better luck.

cause more damage .

Install a high wattage resistor and measure the voltage across it. That should tell you its power rating.

FWIW, here is a user manual and circuit diagram for a model 66A: ftp://bama.sbc.edu/downloads/taylor/66a/Taylor66A.pdf

This site suggests that your sig gen was manufacturer around 1956:
