Hi Dan,
Not that it matters much, but are you absolutely certain that the current
3CX800/3CPX800A7 tube products sourced from CPI are not of Chinese origin
and instead supplied to CPI under an OEM outsourcing supply agreement with
bespoke Eimac labelling / badging done by the China tube factory?
Also I'm curious about the rationale for using two little puppies in
parallel instead of a single 3CX1500A7/8877 tube...it sounds like you have
given this key decision a lot of thought?

Gary, this is a myth, quite frankly, saying the days of this tube are
numbered. Do you have facts to back this up?
>From experience I'll share with you that I can cut a Purchase Order to
Eimac (CPI) tomorrow for any number of 3CPX800 tubes and receive them
about 90 days later. No-one in Palo Alto, CA has mentioned anything to
me about stopping production of this model.
I'm trying hard not to turn this into an advertisement, but for
comparison, we sell the identical tubes you mention (CPI / Eimac) for
under $700 new - and my invoiced cost per-tube from CPI is well below this.
Genuine Eimacs - not Chinese, etc.
