Amp Design Concept -- Preliminary

Power transistors that are designed for higher voltage are more linear and -much- more reliable than those designed to operate on 12-14 volts. This switching power supply bumps up the voltage to 28 or 50 VDC and allows the use of such transistors. 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... www.telstar-electronics.com 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 |
