Title: 8150 tubes Post by: rsumperl on February 22, 2010, 04:54:07 PM 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.

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. Title: Re: 8150 tubes Post by: Pete, WA2CWA on February 22, 2010, 08:25:27 PM Ed Clegg and I "did a deal" back in the 90's for about 15 of them.

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.
