F6 build

At the moment, F6 my favourite Pass amp. 🙂

Actual specifications of my build now:
Power supply: +/- 29 VDC
BIAS is slightly more than 3A.
I using IRFP064N FETs, 0.4 and 0.5 Ohm source resistors, LM329 voltage references.
Output offset dancing slowly at around +/- 10 mVDC.
It has built according to variable second harmonic schematic.
Heatsink temperature is 95 Celsius.
Ambient temperature is about 18 Celsius now, so it is not your summer amplifier.

Well, you can't say, Gyuri, you aren't a Fearless Burning Amplifier Builder.
