Hi Jim

The only manufacturer of the 3CX800A7 outside of Eimac is Svetlana. Morel
Grunberg, 4X1AD, did some investigating on this matter a couple of years
ago. And found the the Svetlana tubes to be 35 USD cheaper. Not all that
much of a savings to justify the extra grief. Now that Svetlana has pulled
up stakes in the US you have to buy them from dealers when they can get them.

Here's the URL for all Svetlana Vendors:

Be advised that VHF Amp builder K1FO states the 3CX-800s made by Svetlana
are actually 3CPX800s with 3CX800 stamped on them. They are manufactured to
withstand a higher plate voltage and require slightly more drive. But they
should work ok in any application that uses the 3CX tube. They would make
an excellent candidate as a replacement for the 3-500 for someone looking
to retrofit an SB-220 or L-7

73s
