If the amplifier has feedback and it is not handled correctly, this can cause stability problems. Futterman knew that ESLs were a likely load and it seems that he knew to be careful about how he set up his feedback to prevent oscillation.

Only OTLs i have owned are Yours ..... an have tryed the Feedback at the input of the frist input tubes grid...but always go back to no feedback....is your setup the way you are saying is the right way to use feedback...an not on the cathoid of the input tube?..... like i see on alot of tube amps...........Dose this help with stability problems on any Tube amp OTL or pushpull?

Vary cool about the Kits.....thanks for your time an for Saleing Kits again.......
