Are there out on the forum any members who have built, planning to build or have knowledge of an output transformerless valve audio power amplifier using those big power double triodes such as the 6336. I believe Julius Futterman designed such an amplifier some years back but have been unable to locate any details of his design.
The idea of this concept sounds interesting to study and any leads will be appreciated.
