Could someone explain the difference in Class A vs Class B amplification? (Layman's terms, please)
That's a well-written reply, my only concern is with the implied definition of class B as push-pull and class A as single ended (though perhaps I misinterpreted the wording) - that may not be entirely correct, IIRC. Class B and AB amps are always push-pull, and single-ended amps are always class A by definition. However, not all class A amps are single-ended. Class A amps can be designed to run either single-ended OR push-pull. In a class A push-pull amp, there are different sets of transistors to handle the positive and negative phases of the signal - the difference over class AB and B amps is that with class A both sets of transistors are switched on 100% the time...but each set handles only the phase it's assigned to.When I was trying to figure out what to do to get some more power for new speakers that were bought I eventually went the way of adding a power amp for my mains and kept my receiver. I was also unsure of the differences between the various classes. Here is a link to the great reply I received from JCD (one of the mods here). Hope this helps.
