Can this schematic work? 6N6P driver with 6C33C-B OTL
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?

Or if anyone has different OTL schematics? please send me.
Schematics from brands as Graaf or Lamm are more then welcome. Here a update.

Design goals:
- 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.
