This sounds really interesting! I would love to get my hands on one of
these to play around with for a while. I checked the Eimac/CPI web site,
but did not find anything about it yet.

> Eimac Offers New Radio Power Tube
> The Eimac division of CPI is out with a new power tube for radio
> transmitters that will be on display at the NAB show.
>
> The air-cooled 3CX1500D7 ceramic metal triode operates at 5 volts, 30
> amps. The company said it delivers the same performance in many
> applications as a pair of 3-500Z glass tubes.
>
> "With output power capability above 2 kilowatts from this single new
> tube, actual usage at 1500 Watts does not even begin to approach the
> design limits," according to spokesman John Allan in the company's
> announcement.
>
> "Mounting is in the same SK-410 socket used by the 3-500Z, and the
> filament voltage is the same. Since the 3CX1500D7 filament current
> matches that of two 3-500Zs, we do advise that related circuitry (such
> as RF chokes) be checked for their ratings if this tube is applied in
> a retrofit. It may be operated in zero-bias, grounded grid
> configuration at plate voltages up to 3kV, and may be operated up to
> 6kV with appropriate grid bias."
>
> He said the device will interest equipment manufacturers and DXers for
> use in RF linear amplifiers.
