Are there any replacement tubes available that are pin compatible with the
8875. I have the Dentron 2500.

Thanks,
Mitchell


The 3CX400A7 / 8874 is a 400 watt triode in this same Eimac family - but air
cooled.

Bob Alper, W6KT wrote an article in Communication Quarterly (now part of
ARRL QEX magazine) in Summer 1996
Specifically for Dentron MLA-2500 conversion (Dual 4CX400a)

Of course this is a conversion from a triode to a tetrode tube.
