damianl said:I thought i saw an amplifier here somewhere that uses a transformer for amplification rather than transistors. Am i correct? If so could i have links please.
Vlauga said:I have thought up the amplifier with the passive transformer amplifier of voltage already
If it amplified a POWER, it would actually be a candidate for a Nobel prize.
Not really. Quite old stuff. Was the usual way of amplification before the invention of the triode. Lars Lundahl sold an amp called "Magamp" in the early nineties. What was new about it was the better efficiency. A simplified schematic was in an audio magazine at that time. I tried to find it again, but wasn´t successful. VAC builds magamps for stabilization of power supplies.
Vlauga, I saw your amplifier some time ago and thought that it looked very interesting. It is on my list of things to try "when I get the time".
By the way, what are G11 to G14?
this is no bad idea !
Amplifiing stage without any semiconductor or tube distortion
try JFET stage(Au=1) , good transformer , and MOSFET A-class stage (Au=1) , no capacitor :O)
I try old transformer from 8:1 100V "wire" radio distribution (in Slowakai 30 years backward :O) and sound is very fast and impressive...
