[Amps] anyone build an amplifier use 6T51 glass buble?

[Joe Subich, W4TV]

I worry about it ...

800 W plate dissipation is marginal for 100% duty cycle modes like RTTY
at 1500 W output.

The specification sheet lists only oscillator operation (e.g. industrial
heating, etc.) and gives only class C parameters.  What will the IMD and
efficiency be in linear operation (AB1, AB2)?

Are sockets readily available?

Those questions aside, the price is very tempting (until the
manufacturer gives up on it).
