Frank, just how much do you think this amp is going to cost? Sounds
like It's going to be out of this world with all the stuff you are
talking about...

50 volt power supplies are very cheap to build. if you have the right
connection with parts suppliers less than $10.or less figure $ 20 max.
Money spent here will also save money elsewhere in the amp. Its a pain in
the but to build a decent amp that works of of 12 volts. 50 and 100 volt
amps are easy.


When it comes to designing a good amp there is no reason to reinvent the
wheel. There is better stuff out there to use than there was 30 years ago
and its much cheaper now than ever but for the most part amp design hasnt
changed much. For what improvement have been made I see few amp builders
taking advantage of them, the same crap designs that have been around for 30
years Most people who can get an amp to work at all think they have done it
RIGHT. I see people who have tried to get 10KW out of a 12volt amp and my
hat's off to those that pulled it off but this is still some **** poor
engineering
