Just finished one mono block 6C33C SE amp.To keep things simple (power supply only need 220V), I used a single driver tube (the second tube is there for backup if not going as planned) through an interstage transformer. Power supply is still regulated but used 6080 instead 6C33C. There are two tube rectifier, one for B+, one for negative bias. This amp used oil cap everywhere except two electrolytic for the heaters for the driver and output tubes. The amp measured better than I planned on the bench, power is a whopping 22Watts with 5% distortion, with 10% distortion it is up to 27W, this put the amp power in 845 territory. The level of distortion across the audio band is also much lower.
Can't wait to finish the second one to hear them!
