I have a box full of 6n6p and 6c33c-b tubes. I saw a OTL design with 6c33c-b tubes but with a other driverstage. A nice driverstage i saw by triodedick. The ecc99 is almost compatible with the 6n6p tube. So i combined both schematics.
Who can tell me if this will work?
- Cancelling powerrail noise/hum
- Correct gain differrence between upper/lower outputstage
- Fixed bias between 200 and 250mA
- Simple power supply
- Use 6n6 and 6c33 tubes
- 20 Watt output at 8 ohm
The input SRPP stage has a 11 x gain this looks to low. But my input signal is 4 V.
