This is interesting project with 307a VT-225 pentode and output transformers from old radio receiver with EL84 tubes. Cheap project, but great DHT or DHP sound, I prefer it triode strapped! And as you can see no enormous space is needed. I have also tried this 307A amplifier RH connected with really good results.

    Ciao Antonio,

    Great amplifier, did you try other types 307A except Ken-Rad, which are other tubes in your amp?
