Overheating JVC receiver?

[[email protected]]

I just ordered a JVC RX-D302B receiver from Crutchfield. Actually, this
is #2 - I sent back #1, a scratch-and-dent, because it quickly became
almost too hot to touch on top and filled the living room with the
smell of hot circuitry. It seemed to work fine otherwise, no
overheating shutdown, but still. Now #2, which is new, is doing the
same thing, and I'm wondering what is going on. Is this normal? I'm
using Polk Audio R40 speakers.

What are the operational conditions when this nastiness happens?

If it happens when you are playing your system loud, maybe no problem.

If it happens when you just turn the receiver on, with no speakers or other
cables attached, then you have a problem.

You could have one or more shorted speaker cables.

Just when it's playing normally. I'll try replacing the speaker cables.

Is the receiver installed in a cabinet, or out in the open?

Suggest you ask here:

rec.audio.tech

But if you're nervous about your hot receiver, I suggest you return it
and get a receiver that runs cooler.

It's in an open cabinet. I tried unplugging the speaker wires and it
still gets hot and smells - not quite as much as before though.

Definitely check your speaker wiring for shorts of some kind.
Either that, or there's something wrong with one or both of the
speakers themselves.

Have you tried another amp/receiver (not receiver nr. 1, but an
entirely different amp) ?

I'd return it.... I could only find 2 user reviews on this thing and both
complained about overheating and early failures.

I remember I had a Toshiba amp once. It worked fine with ordinary
speaker wire. Then I tried some fancy QED wire and the output stage
blew. So I went back to ordinary wire and never had any more trouble.

Well isn't this another proof that wire is not wire?

Who knows, maybe there was a problem with the installation of the wire.

Oh Arny. I'm not as untechnical as all that!
