Care and Feeding of Power-Grid tubes.
It's always good to see a manufacturer acknowledging their history.
CPII https://www.cpii.com/ are the current owners of the designs and IP [intellectual property] of EIMAC [Eitel-McCulloch] who designed and manufactured a whole bunch of 'hot' power-tubes in the 50s/60s/70s and which are still being used today by us RF-fiends.

[I never understood the 'ultra-linear' audio-amp thingy]
