80W Tube Monoblock Amplifier

My goal was to design a high-powered wide-bandwidth amplifier with the finest sound and to keep it simple but not too simple. I rejected single-ended (SE) designs because of their low power and limited bandwidth. I wanted to see if I could get similar sound quality perhaps better with an efficient push-pull design. And I wanted to do it my way.

2 x 40W Valve amplifier

In the the valveamp schematic below you see that the amplifier is built with only 5 vacuum tubes!
The circuit is a classic push-pull amplifier using an output transformer with a center tap.
This topology is widely used for tube amplifiers, because it is impossible to make a complementary P-type tube:
you cannot make holes in vacuum as you do in semiconductor materials.

Tube Line Preamplifier Project

The interest for circuits of tubes, remains big. Thus I will give completed in enough big degree, circuit of preamplifier. It is mainly constituted by the department of main preamplifier, the department of input selector, delay of application voltage and connection output of preamplifier with the final amplifiers and the department power supply. The department of mainly preamplifier appears in the Fig.1. Deliberately it does not have something revolutionary in the designing. In the entry exists a simple circuit constituted from relay that is drive from input selector [S2]. The signal afterwards drive to the next stage that is constituted by a circuit cascade S.R.P.P (shunt regulated pushpull) and a circuit cathode repeater, in the exit.
