6C33C Tube Amplifier Schematic

Web otl = output trasformer less tube amplifiers my consideration on problems of each design: The tricky part was to get the right amount of feedback, which according to graaf is about 6 db. Ciclotron balanced design problems (type 1): Ibrid 6c33c otl by shinichi.

Lee 6C33C Otl

I want to use design by hans beijner. Web i have interest to built an otl (output transformerless) amplifier using 6c33c tubes. Web the obvious choice of output tube was the russian designed 6c33c triode, because a single pair can deliver 2.5a into an 8ω load from a moderate 150v rail.

These Are Excellent Sounding Amplifiers With Huge Transformers.

I found ~12 db better, also less hummm. Can anyone sent me a detail schematic with component. Web in the power supply, i adopt a vacuum tube rectifier ( 5v4g ) for 6sn7gt input stage.

The First Capacitor After 5V4G Rectifier Must Be Paper In Oil Type.

No not yet but one channel bias very.
