Leaving theory and implementation aside, all things being equal (which they rarely are) Class A operation generally sounds better. I don't think the schematic will tell you anything, but if you turn the amp on (safest if connected to a load) and leave it on for 15-20 minutes w/o actually passing a signal thru it, you should be able to tell immediately. Amps that operate in Class A would be v warm to hot at idle. If the heat sinks or case over the output devices is only warm, its not class A. Also if the case does not have any external heat sinks, that is a clue that its A/B. For what its worth, I don't remember any Tandberg amps operating in pure Class A but its been a long time so I could easily be wrong on that one.
Can someone tell me the Class of my Tandberg amp
I was wondering if someone with a little more expertise could chime in and look at the diagrams and figure out what class the amplifier is. I know that the class A's are usually the most sought after, or AB. Isn't this a classification of their efficiency? If so why does it translate into better sound?
