A while back I posted questions about troubleshooting a Technics AV
receiver that had suddenly just quit on me.

After doing everything I was able to do myself, I took it to a repair
shop. They called yesterday and said the audio outputs were blown,
and that it would be $100 to fix it. I told them to go ahead and make
the repairs.

I'm curious, though. Do I have to worry about this happening again?
I definitely didn't drive it hard...I was using it at the time to
mainly listen to NPR.

I'm also sure that the speakers weren't shorted. The receiver worked
for about a week, then just quit.

Am I doing the right thing in paying to have this repaired, or do you
think there could be a bigger problem that could cause it to happen
again?

The speakers that were connected to it are $40 Audiosource 8-ohm
speakers. Any problem with that?

If the receiver has a lot of years on it, it is possible that some of the
caps also went defective, and thus cause some problems. If the service tech
is experienced, he should normally check everything out, that could be a
problem.

As for your speakers, you should take them to the service centre to make
sure that there are no defects. It is also possible that a part in one of
the crossovers has failed, and caused the problem. Ask the tech if he can
check the speaker units, and the crossovers.

In the past, I have seen power transistors, and or IC's have their retaining
screws that hold them down to their heat-sink, become loosened up. When
this happens, the thermo contact between the device, and the heat-sink
becomes poor, and the device can easily overheat. This can occur from the
effect of the thermo expansion and contraction that is generated from the
temperature changes during the use of the unit. This however, is rare, and
mostly happens if the retaining screws were not tight enough in the first
place.

If your receiver is serviced properly and not abused, it should give you
more service for a very long time.

my opinion;
if it has a IC final ("SVI" type) you are better off w/ a new receiver.
