can a picture tube be used as an RF amplifier?
Hi,
I get a lot of broken TV's for scrapping from time to time, and it seems that just getting rid of the tube in the trash is a shameful waste. But I do know that these are about the only remaining vaccum tubes still in manufacture in this country. I understand that most of the power is supposed to go through the electron gun of the tube, but I wonder if the electron gun could be reconfigured as a linear final? Bad idea? The Eternal Squire |

usualy the electron gun is designed to generate a few tens of
microamperes of current. i don't suppose you'll get the full legal power from it! |

I doubt that he would get more than a couple watts out of a CRT, even if it has 30 KV on the second anode. The ICs used to drive a computer monitor's CRT, on the other hand? Some will work on two meters, and higher frequencies and can be found in dead monitors all over the place. -- ? Michael A. Terrell Central Florida |
