Hybrid Amp, Tube+MOS FET SE

I have completed to make a Hybrid Amp using tube for
voltage amplifier and MOS FET SE (source follower) for
output. The measured results are shown in the attached
file.

The sonic is clear and wide ferq range.

Looks like a good circuit, I bet it sounds great! I like tubes but don't have a problem with Class-A MOSFET output stages

Yes, I encounterd a big problem at MOSFET. It was cooling
problem. Finally, I used a forced air heatsink with heat pipe
scheme for Core Two Duo CPU. Before this heatsink, 6 MOSFET's
were destroyed.
