thunderchief at 18V

[nooneknows]

ciao,
I've tried the thunderchief dist and, although it has a great sound, I think it's a bit to compressed to my ears.
So I decided to raise a bit the voltage... wow! with to 9V batteries in series there's a huge headroom: I had to lower the source resistor of the first 2 stage to 820 (and it was a bit tricky to bias at half voltage the drains).
But the crunch the circuit has it's really nice.
Please have a try and let me know,
bye!
