Patents

Hi Folks

I must make clear that what it is in my post #25 is a qoute of Tubecad .com.

The SRPP is a controversial circuit. Even its name is not set in stone, as it is called the SRPP, the SEPP, the mu follower, the mu amplifier, the cascoded cathode follower, and the totem-pole amplifier. Interestingly, the name given in the 1940 patent (US 2,310,342) for the circuit is seldom used: a "balanced direct and alternating current amplifier."

I think is is clerar now! ....the rain is gone...llalalalalalalal..................

Cheers

PS. Now i see that when anybody gives a link...no one does the home work!

- So anyway, what, exactly is wrong with the design? Suggestions on converting the circuit to active?
