LPD,
I guess you know that the rectifiers and 6SN7's have audio applications. As far as the other tubes, pull the sweep output tubes 6BG6, etc. BTW, 6BG6 is a good audio tube also.
If you run across any color TV's that have 6JE6 sweep tubes please grab these tubes if its not much trouble and the 6BK4 shunt regulator, damper and HV rectifiers. I'd gladly pay the postage if you want to send them to me. I could use them for my color restorations.
All tube set color TV flybacks are also a good thing to grab.
