I recently purchased a sony amplifier after having problems with three
yamahas... it sounds great and is working great but it seems to get
real hot after a short amount of use. Is this normal, should i worry,
can i do anything to prevent it? Any help will be much appreciated.

It really shouldn't be getting that hot. You may have a problem with your
speakers or wiring, running to many speakers, or using excessive volume /
tone settings. These things aren't PA systems.

Even 35-40% volume setting can be too much if it's on the Tuner input, the
way those idiots process the sound, especially if you have the loudness or
"super-bass" turned on.

How hot? Too hot to keep your hand on any part of the case for more than a
minute? That's too hot!

What are the operational conditions?

Is the amp well-ventilated?

You could check whether one or both of the speaker cables has a short
somewhere.
Surprisingly, this wouldn't render the affected channel totally
silent.
What kind of speakers do you use? Do you have several speakers
together in use? What is their impedance?
Is the amp well ventilated or crammed into a cupboard ?

*Real hot* is a very subjective assessment as is a *short amount of use*.
Have you measured the temperature ? How long does it take to get hot ?

Does it get hot even when idling ( no signal ) ?

Not sure if Sony make / made any class A amplifers but if so , then
running 'hot' is normal.

What problem did you have with the 3 Yamahas ? Maybe there's something
with your setup that gives amps a problem ( various possibilities ).

My Sony ran hot (and also blew a rear channel on two separate occasions). I
discovered after the fact that the now-ES versions were notorious for that
"feature." Very high operating temps (hot cup of coffee hot) aren't good.

Insure the amp is in a well-vented location (stacking your dvd player on top
is a no-no). Enclosed shelf units trap heat. I've since modified my
component enclosure with a small whisper fan running from the receiver's
switched input. Everything runs cool.

I am inclined to agree, I am surprised by 3 problem Yamaha's. The Sony is
not a class A amp - I don't believe any of their current units are. The
Sony's have had complaints of getting very hot. I would check for other
reasons.

I have a Technics that is A. It runs very hot. The case is sometimes hot
enough to be uncomfortable to touch, but not so much as to actually burn
your skin. The heat sink chimney will burn you I think (I haven't tried
this). I have a dial thermometer sitting on top of it and it is usually
pinned at over 140F. It has always been like that even though it gets
hottest at idle and cools down when playing. Other people who own this
monster report similar concerns. This is because of a fan that comes on
based on output level. I have had it for three years and it hasn't failed
yet... all that heat can't be good for it though...
