Hi Everyone. This is a project I started a while back and finally am getting around to finish. A push-pull 832 amp. I love the way the tubes look but they are certainly not mainstream audio ones. Typically used for really high frequency radio power amps. Still the current price for such a cutie is only $10 from Antique Electronic Supply. Since I already had them and the amp was at least started I figured it was something to keep me out of trouble. I am actually running the tubes well below their ratings and really just at the bottom of the linear range 250 Volts and 51ma each side. In class A pentode mode I figure on about 7-8 watts. Driver is a 5751 in SRPP mode. The photo is what it looked like when I set it aside. More to follow as I work on it. It was barely operational at the time (hum, noise and so-so sound). I figure I can make it sing with some changes.
Good Listening
Bruce
