Integrated as Pre amp???

I'm using my integrated amp as a pre amp to feed a power amp. For some reason it still gets really hot. Surley it would be the power amp section that causes any heat, and if there are no speakers connected shouldn't the amp run cooler?

 

That TAG pre-amp is a class A design isn't it? That would be why it gets hot still.

 

Its a tag integrated and a power amp that Ive got. I didnt think it was class A but you're probably right, as that would make sense.

 

I dont think it is Class A. The TMA thought that inefficient and went A/B.

I've just read that
"As you may remember, most amplifiers are Class A/B. This means that there is a small amount of current running through the output stage (Class A) even when no music is playing, and at low levels of sound, this current goes to the speaker instead of being dissipated as heat. At higher sound levels, the current has to be turned on (Class B). Depending on how much of the power is in Class A vs. Class B, the amp can run hotter at idle than when the music is playing loud."

This may explain the heat!
