old receiver Sony problems

[powrslave]

<font color='#000000'>I have an old (10year) Sony S series receiver...
I'm getting PROTECTOR error messages sometimes on the screen forcing me to turn it off.

Could this be an internal short or two analogs touching?
Any clues...
I love this receiver but it's time for an upgrade.

<font color='#000000'>My experience when an amp's protection circuit engages is almost always detecting a short at the transistor output. Or a defective power transistor in either channel.</font>

<font color='#000000'>If speaker wires are frayed, at either end, and a part of the wire is touching something else, can cause this too.
Have you recently changed speakers? This is also a common problem if you're trying to drive 4 ohm speakers, with a receiver thats meant to drive 8 ohms. It will make the receiver run very hot, and get this message. It's a safety feature, to keep from burning up the receiver.
Good luck!</font>

I recently moved and had to set things back up.
I'll check the wires.

As for the ohms, I'm using booze series V 501's and I think the ohm rating is 6.
The receiver allows for either 4 or 8.
Which one should I use? 4
IF it is set to 8 could that be causing the issue I wonder?</font>

Actually if your receiver has an impedence selector you should keep it in the 8 ohm setting. So long as it doesnt become unreasonably hot during prolonged use. If you've been using the 4ohm selection all this time then you'll want to monitor your receiver in the 8ohm setting until you can be assured it's staying cool enough. If your speakers are a 6ohm load then I doubt very seriously you'll have any excessive heat issues.
