Default Maestro soya amplificador

Described as - 'S>Soya 811A Direct coupling Amplifier' (cct. attached) I built this after finding a pair of TZ40 valves. I used a 15K output transformer to suit. It worked well, but insufficient gain for my needs. I then tried the '811 SE Positive grid Amp.' (as attached) with much better results (with & without feedback). Anyone else played with these configurations?

Hope the attachments are visible!?

Any observations welcome,

David.
