Tube amp transformer

> 7 pin tv tubes that will give you a watt or 2 in push pull.

In two bottles.

The cuteness here is the twin triode for the entire P-P power stage. Worked great for me for a hi-fi headphone amp in the 1970s when tuner-tubes were a glut on the market. But gee-tar? How many primarily triode power stages do you find at Guitar Mall?

There are a few twin-pentodes but most are awkward. Strange sockets, dissimilar sections, far too big for bedside, etc.

Yes, you are right, I got that wrong, 340v on the Anode/Plate.

340VDC from 250VAC is expected. 340V is within sight of voltage rating for the usual utility triodes. Current or power could be out of sight. Back when assorted tuner tubes were 2/$1, I didn't worry too much about 50 hour life.
