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?

Thanks Again,

Nate

I too don't think that Tandberg ever made a pure Class A amplifier, and just a small minority of amplifier manufacturers have.

I suspect from your other recent post that you are referring to a Tandberg 3003, which is rated at 2 x 165 watts into 8 ohms, and 2 x 250 watts into 4 ohms, and weighs about 25 pounds.

Those figures alone indicate that it is not even close to being pure Class A. The Pass Labs XA160.5, for example, which is Class A and puts out 160 watts into 8 ohms, weighs 150 pounds for EACH single-channel amplifier. As Elizabeth said, true Class A amplifiers "are BIG heavy monsters."
