Hello you all,
I'm working at the project of the pictures. It's a current amplifier with no feedback able to provide 1W to 600 Ohm load with 0,04% of distortion. It can provide till 3W with 0,08%, so it can be used also for high impedance speaker like the famous Philips 9710.
The circuit is based on two part:
Comments and advice are welcome

The circuit is based on two part:
- V-I converter
- 6 time current multiplier
