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.

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.
Web in the power supply, i adopt a vacuum tube rectifier ( 5v4g ) for 6sn7gt input stage. Can anyone sent me a detail schematic with component. I found ~12 db better, also less hummm.
No Not Yet But One Channel Bias Very.
The first capacitor after 5v4g rectifier must be paper in oil type.
