Hansen 10 watt guitar Amplifier.

I have tried before. to make a Push-Pull amplifier with ECL86 tubes. It was a failure and ended up becoming an AC-15 type.
It turned out that the power supply did not work, the old cilium rectifier and the old smoothing capacitor could not deliver stable excitement. With a new rectifier and capacitor, it came to play just fine. On the forum 18watt.com I was introduced to the Marshall 1930 Popular amplifier as just was with 2 pcs. ECL86 pipes. As described elsewhere, this amplifier is ready made and sounds as expected. I will try again with an amplifier with two ECL86 in the output stage. But also this time it must be made of new components.
I have modified and drawn the following diagram.


I have drawn the following Layout for power supply and amplifier.

So much work, and so "failure". It simply did not work. Something had to be done. So one turn on the shelves for alternative components and then back to the drawing board. I found some ECL82 output tubes and 2 preamplifier tubes ECC82 and EF83. ECL82 has a different leg configuration than ECL86 and all tubes have a smaller reinforcement than those previously used.
The diagram was drawn once more:

A new layout was created on the existing Turret Board.

With voltage connected, the amplifier played really well but there was an annoyingly weak hum. With a little teaching from Bjarne Hansen, the anode and cathode resistance values were changed so that the individual tube gain times the value of the cathode resistor gave the value of the anode resistor. It provided an almost silent amplifier that plays with the selected tubes with very little distortion and yet abundantly high for home use.
I have designed a cabinet that in the future will be the model for my amplifiers that can just be 2 12 "speakers in, so anything below in size can be there, for example 1 x 12"; 2 x 10 "; or 4 x 8".

The amplifier is equipped with 2 12" "Hansen" Speakers.
