Hi Ken and all.
I suggest you go to www.eimac.com and look for the solution there. Took a
quick peek myself, lots of info and links that may help you find the answer.
They may have the capacitor value listed, and if they do not, drop a short note
the parent company, (CPI) they will probably tell what value is which. I have
found them to be very forthcoming with this sort of odd info even after I have
mentioned that I am a ham operator.

Subject: [Amps] 4xc250b Valve Bases - Screen ring capacity - HF v VHF
Hello all,
I have a couple of 3rd party bases for 4cx250 valve bases but am unsure
if they are designed for HF or VHF operation. I know that the capacity
of the inbuilt screen grid capacitor was different between HF and VHF
bases. I could check this (roughly) with the capacity function of my DVM.
Can anyone point me to the approximate capacity I should see for HF and
VHF bases?
Thank you and 73,
Ken.
