Got the schematic, found the voltages off the 25Z6 were 40 volts low.
I clipped the leads to C1 and jumped in a couple new caps and viola, the B+ popped up to normal and the sound started coming in loud and clear!

I can tune a picture too but the tube is so shot you can only see it in a dark room and only if you keep the brightness down to half, anything higher than that and the tube goes negative, pretty much acts just like a bad 7JP4 does.

I have 22 volts on pin 2 of the crt and 80-175 on pin 3 depending on the brightness setting.
