6cd6

Just wondering if the 6CD6 was worth playing with in either a SE or PP configuration. Why? I just happened to have a shoe box full.

I've no experience with this tube so this is just speculation...

I think I would be tempted to try them in a similar circuit to Gary Pimms 47 PP amp... It looks like it will work nicely in such a configuration.

Are you feeling sorry for yourself?

Or just trying to bait me into responding?

Lesse...6CD6 sweep tube...20W plate dissipation, 15 W heater.

Can easily do an ampere of plate current, but would require higher screen or grid voltages (200V+ scr. or maybe +5Vg).
Could try it in triode mode as a substitute for 6AS7 I suppose.

Hmm, bigger ideas...PP amp, class B (or very nearly so), low impedance to take advantage of that high peak current. Probably 50-60% efficiency easily, so up to 100W output without red plates I would guess.

I've used it as a driver for a plasma tweeter circuit.
