This amplifier is designed based on the Mullard 5-10 amplifier.
I have made some adjustments on the shematic.
I overtokk this amplifier half finished. There were components to
indicate that the previous owner had planned to make an audio amplifier.
All the major components and the power section was mounted.
I soldered up the rest even after drawings from Mullard.
I do not know the specifications of the audio transformer.

20 Hz - 20 kHz : -1dB
