[Amps] Cetron 811a.

[Ulf (SM0NOR)]

Hi all,

I recently bought 4 Cetron 811a from Nebraska Surplus, date coded 1988.
I intend to put them into a home brewed amp that is real close to smoke testing.
Is there any start up procedure that is recommended for NOS 811:a? I have not come across any recommendation regarding this so far. But before, I put them in and apply filament and HV, I thought i'd ask here.

Thanks!
