anyone seen this before?


 

This amplifier is not a "Bonavolta design". It is a copy and paste without permission from my article "Un amplificateur pour casque électrostatique" in the french magazine L'Audiophile" (May 1990). In my article I clearly indicated that this circuit is based on the "Stax Circuit B". This amplifier works very well with some modifications : use 180K and 270K feedback resistors and + 245 -370 volts power supply voltages.

I would say it was more than just based on the Stax circuit...
