hey, anyone built a hybrid with high voltage SS output
or are there any experiences with any kind of high voltage SS output
would it make sense to use a flea power amp as driver
maybe either OTL output, or maybe even a 2A3

While their not hybrids, I've built amps that are high voltage SS. The amps are solid state renditions of the 47 P-P and Tabor class A balanced amplifiers with local feedback on the output stage.
On my webpage-
Tube versions - 47 P-P, Tabor, Tabor Rev. 3
Solid State versions - SS Tabor

Here's another example of a SS high voltage output circuit with an OPT and local outstage feedback.

I started with a hybrid of MOSFET input and a 6L6 output tube, then for grins substituted a HV IGBT in place of the tube. I think it may sound a little better with the SS device but it's a difficult call.
For a hybrid, the depletion mode MOSFET at the input could be replaced with a pentode., which will certainly have the possibility of changing the low order harmonic content.
Cheers,

Hi Gary
Very impressed with your SS Tabor amplifier.
I have built a few transformer coupled amplifiers Amity, Karna, KK and variants (all DHT outputs).
I have noticed the input tube has a big impact on the overall sonic of the amplifier and I just haven’t found an input tube I like.
What are your thoughts if I used SS input TT coupled to 45 drivers and 300B outputs? This would do away with a tube input.

Frank
