Edit and off Topic: As you seem to have a lot of knowledge in tube Amplifiers, I have here an old Czech tube guitar amplifier called Attack Power. Using 3x ECC83 and 2 EL34. Do you have any information about Czech guitar amplifiers? Would be nice to hear from you!

Cheers, now I take a Budvar :drink:
This is his homepage: http://web.quick.cz/rozdall/
These are Marshall copies. I´ve heard both positive and negative reactions about his production, these amp are quite low budget amps, but he is setting quite high prices these days, which sucks.
There are some better guitar tube amp constructers such as:
ESH - www.eshamp.com
HOT (Pavel Horký) -these are great Mesa Boogie like amps - www.hotamps.com
George Dennis - http://www.george-dennis.cz/

hope this was helpful;)
