LU1014 anyone? While Lovoltech seems to have disappeared the devices show up all the time.

Zen Mod. I fully agree with you that I am not suggesting new hair-brain ideas. All I am saying is for lhquam and others to expand the scope of understanding and characterize the full potential of their Conceptual F6. We are still talking about the identical build; but with different operating conditions. Knowledge can only be bliss. All bets are that Mr. Pass operates his F6 in Class A. But; we know very little or nuttin' [as you put it] about it.

ZM. Thank you for the schematic. On classic papyrus? The Thread "F6 Amplifier" is truly a wealth of information for DIYers to tap in for the ultimate in flexibility of their hobby. Like patents and other gizmos, new and improved amps are built on the shoulders of older ones.

The challenge that I am undertaking is to Guess where Nelson is taking us. That means KISS (Keep It Simple, Stupid) and quality, which involves trade-offs. I suspect that Papa will show a circuit that is even simpler and better than mine shown in post #1647 F6 Amplifier.
