Yes, a little bit ;) .

The schematic is correct and the amp as shown works. It has been operated for more than 1 year without problem.

I would like to mention one thing: I do not intend to recalculate or to rebuild this amp for ordinary transistors like IRF540/9540. It just happened that I had a good stock of 2SK413/2SJ118, so I made this amp, and it is tailored for these transistors. Provided anybody understands well its operation, he can recalculate the resistors.

This amp was never intended as a DIY project. It was the way for me to verify error correction principle, and the hint given by Nelson Pass.
