Greetings everyone,
As anyone played with 8150 tubes? They were sold as "RF" tubes for mobile transmitters and thus have a 12 v filament. They have a plate dissipation of 35 watts and a max plate voltage of 750.

Clegg 22'er MKII, 2 meter transceiver, uses one. Probably others in the VHF amateur radio circle. I think they were also popular with the 2-way radio manufacturers.

Cool tube.  Kinda looks like a 6146B in a 12 pin compactron envelope.
Full ratings through 60Mhz.

Ed Clegg and I "did a deal" back in the 90's for about 15 of them.

National designed 6 and 2M transverters with that tube in the final. Only a few prototypes were made and the project cancelled.

I have an Amplidyne Labs 621 that uses the same tube. I have been rebuilding the transmitter and I have it working on 6 meters into a dummy load. It seems to be a very rugged tube for its size.
