8417 is expensive because of Wawassee Electronics. They used it in amplifiers for RF. Very non linear amplifiers.

Although I mentioned the 8417, I wasn't suggesting it as an RF tube. It's a beefy pentode designed for ultralinear audio, which it does well, and nobody knows what it is, which is part of its appeal to me. It IS way overpriced in the markets of today. Maybe I should just sell the NOS pairs I have...

I like any tube whether it's RF-purposed or not. Takes more than an RF tube to make a radio set.
I find the 8417 interesting personally, Its low grid bias for one thing. just costly but never mind me,
Steve- Announce and let the volunteer loose!!

The 8417 is an excellent audio tube and perfect for modulator use. My Johnson Rangers have been converted to them using a phase inverter instead of that lousy driver transformer.
