Default What have I done to my reciever?!?!?

If the fuses are ok then you blew the outputs. Fixable if they're decent
recievers, but probably not worth it if they're worth $100 or so.

Next time install some sort of switch on the output so that only one
reciever can be connected to the speakers at a time. I'm really surprised
you didn't blow up one or both amps sooner, even if one was turned off.



Thanks James!
Just curious ... what would actually have been destroyed in this scenario? I
believe every single speaker output was rendered non-functional - even
outputs that weren't hooked up. Also, there was no burning smell on the
"good" receiver.


If you look at the answer again you'll see the word 'outputs'. This
refers to the output devices in your receiver(s). Different ones use
different types. Some have discrete transistor devices. If one of
those, the output transistors and possibly other components associated
with them are now defective.

Troubleshooting one of these is more difficult--but not as expensive to
fix as the other type--that type being a unit with most of the amplifier
circuitry encapsulated in an epoxy module.

Those modules are easier to troubleshoot because for the most part, the
devices which will fail in such a scenario are all within that one
module. Replacing the one unit will likely fix the problem. OTOH, the
price for the part is higher than the various discrete parts in the
first type. Replacement is more difficult in some cases because of
soldering the number of closely-spaced pins involved. Many of the
modules are discontinued and difficult to find.
