Bob:
>>From old notes: IPA Grid 8 to 10 mA
> IPA Screen Volts 200 volts
> IPA Plate Volts 2.5 kV
> IPA Cathode 215 mA
> IPA Bias None
> PA grid 10 to 30 mA
> PA Screen Current 120 mA
> PA Bias -250 Volts
> PA plate 6.9 kV
> PA plate 1.8 Amps

Our 10K ran at 6.5kv & about 2.2 amps plate current, for 8.4 kw out. IPA cathode was around 180 mils normally.

Mike:

Already talked to Gary Liebisch about a 10NV/lt.  Had planned to replace the transmitter in about 2 years, but I suppose 25 years is a good length of service.

Also getting a quote on the BE S series, but that looks like a much older design. At least would have a use for my 802B exciter....

The tube socket is designated an Eimac SK-700, CPI quoted me $6,000 and several weeks to replace.
