THE properties of the amplifier to be described are entirely due to the type of transistor used, and the purpose of this communication is to report on its suitability for the amplification of ...
This efficient MOSFET power audio amplifier based on IRF530, IRF9530 HEXFETs and BC550C NPN transistor provides about 18W into 8 Ω speakers and up to 30W into 4 Ω speakers with a total harmonic ...
Immediately, I learned that the common base configuration gain was 6db lower than the common emitter. This blew my mind. Then I started checking input resistance and was shocked at how low it measured ...
Members can download the PDF ebook. One day, back about 1966, I was going up the elevator at 285 Columbus Avenue in Boston to look at some production problems on Philbrick’s fifth floor. And who was ...
Someone brought a dead Marantz amplifier to [Lansing]’s attention, a rather nice model from the 1980s with one channel entirely dead and the other very quiet. His account of its repair is ...
