You are welcome.
This is the schematic.
The main specs are:
- Series PP topology
- 4W RMS @ 6/8 Ohm per channel
- 1:2 input insulation transformers
- 'Zero impedance' power supply (direct rectification of 220V/50 Hz AC line)
- Philips 12AT7 & Svetlana 6AS7 for each channel
- 2X110V/15V/50VA output toroidal transformers
- 220V/2X6V/50VA heaters transformer
- 10 Ohm series NTC to limit in-rush current at power on
- Predominant 2nd harmonic distortion
Best Regards
Luca
