This is one of my absolute favourite power amps. About 8 watts RMS
output power from a single ended EL34 output stage are more than
enough for a good hifi speaker.
The driver is a simple parallelled ECC83 design.
Both - power and output transformers - come from a Siemens 2524 amp.
The meter is from a bigger model (6SELA 2600).
One of my best sounding amps!
