Greetings,
Looking for some help regarding tube amplifier pushing a square wave through it. Not interested in amplifier that is integrated with solid state stuff. Only a amplifier using tubes. If your interested in helping
please reply and I will detail what I'm seeking to do.

Thanks
Shorty

You might contact Ralph Karsten of Atma-Sphere. His output transformerless tube amps have pretty good bandwidth.

From the specifications page for the M-60 (60 watt monoblock):

"( 1 watt, open loop ) 20 Hz squarewave Tilt; unmeasureable
1Hz-200KHz within 3 dB"

Looking at the specs says square wave. smiles but i need to be able to push at least 5,000 hz. They also looks pretty pricey too. Im not going to use them for sound. Want to put a square wave that i can change the duty cycle on to like 30/70.
Tried it with integrated tube amps and they didn't like the kind of duty cycle and fried some of the integrated parts in them. Need either two or a stereo one and want to take a tube linear amp on each out put to boost the power up. I'm not against buying a kit and etc for doing this.

I'm not an amplifier designer/technician, so I suggest you run this by Ralph.

The M-60 is available as a kit. Apparently if you move quickly you can build one in less than two minutes and thirty seconds. Click on the arrow:
