Can a faulty speaker damage a receiver?

[Rhombus]

Since I bought these Model 10 speakers, 2 receivers have died from similar problems. Can a defective speaker damage a receiver?

[Skynut]

My guess would be yes.

but it is only a guess.

[jcaut]

Yes, it's possible. Depends on what's wrong. Do the speakers sound okay? If possible, put an ohmmeter across the terminals on the speakers and see what they read. My guess is 6-8 Ohms would be normal, and both speakers should read the same.

What kind of receivers have you been killing?

Yes- a short in the speaker and an old reciever without good thermal/ current protection would be a bad combo. check the speaker as jcaut suggests.

First, a Carver 6250 reciever, left channel died, then whole preamp died. The Carver 900 receiver I replaced it with is exhibiting the same behavior, left channel drop outs. I'm afraid its happenning, again. Only difference is: if I place the receiver in mono mode, turn the volumn almost full up, then back to stereo mode, its fine. ...Using a pair of Monitor 10Bs. Tested at about 6 ohms each. I had to replace the left one's SL2000 tweeter, recently. Coincidence, or what?

Update: It might have been a dirty switch, Tape1-Tape2. Switching it a couple of times seems to have fixed it. (crossing fingers) My only question is, why would that only affect the left channel in stereo mode?

While I'm not real familiar with those Carver receivers, I do know that they should have no problem driving Monitor 10's. And, they should have pretty good thermal, and/or short circuit protection. I don't think it's a speaker issue.

The first one sounds like a coincidence, to me.

On the current receiver: I think you have some dirty switches and pots that are causing intermittent connections, resulting in the sound drop-outs. Almost any switch could be the culprit, depending on how it fits into the circuit. If it were mine, the first thing I would do is get a can of Deoxit, (http://www.caig.com/) and treat all the switches and controls. See if that fixes your problem. That should be the first step, because it's hard to troubleshoot other problems if you've got dirty controls.

Also, I'd like to add that the Caig products are quality products. (No, I don't work for them) Some folks have the attitude that the more commonly seen "tuner cleaners" from Radio Shack will work just as well, but they don't.

Thanks...will do.

I'm pretty sure, it was a dirty switch, now.

Sounds a lot like a dirty switch to me....
