The PT15 SE amp is finally done.
Driver valves are old CV1932s.

The amp is very simple.

The PT15s share a common heater transformer and cathode resistors.

The CV1932 driver stage is just a common cathode stage,
capacitor coupled to the grids of the PT15s.

Output transformers are Hammond 125FSEs configured for 10k primaries
And that's it.

Steve

Nice one Steve. Any schematics to share for those of us who are electrically challenged? (If it's not a speaker I haven't a clue)
