Adcom GFA-555 power amp (attached ZIP) question.
Looking at this schematic I don't see D.C. Blocking caps between transistors. I'm coming into Solid State from really not much knowledge of Transistor Amplifiers. I have had classes on Electronics which discussed BJTs and FETS etc on a component level. But I know very little about the application.
That said, I've worked A LOT with tube amps and have experience there. In a tube amp the next stage has to be coupled by a coupling cap which blocks the D.C.
Where are they at in this Adcom schematic? Why doesn't it need them?
Lastly, is there a good place to learn the basics about solid state power amps on this site? (Wiki, FAQ, etc?)
thanks!!
