There are many good solutions in the DIY community, but nothing seemed satisfactory to me. After looking at different circuits in the Internet, I have decided to calculate my own 2A3 Amp circuit design.

This is revisited schematic!
See details at Upgrades page.

The original schematic can see at its own page.

Developing this amplifier has taken a lot of time. All the hard work is done for fun. If you like building it, if you want to support further upgrades and sound improvements or if you want to say simple "Thank You!", please make a small donation through PayPal.
