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:drink:
