Fuse burned out in shipping? ?

Aewhistory,

The only way to tell if the amp had a blown fuse when you received the amp from the shipper was if you checked all the fuses in the amp before connecting it to the AC power.

The more practical, likely, explanation is the fuse blew when the amp was powered up in your home after you received the amp.

I would suggest you try another fuse of the same type/rating. Before doing so I would suggest a visual look around inside the amp for damage that may have occurred during shipping.

If it blows another fuse right away.., then the seller was cheating you.

Disagree.
I am betting the fuse blew when Aewhistory hooked up the amp and turned it on.

Was the amp damaged in shipping? Aewhistory says the amp was poorly packaged.

Also it is not unusual for a shipping handler to drop a heavy item to the ground/floor/stoop from a standing position.

So the next question might be was the outer case, cabinet, enclosure, of the amp damaged in any way? What did the shipping box look like? Any evidence of excessive abuse?
.

The above answers are intelligent discussions of what may may have blown the fuse, but none even hint at an unplugged amp blowing a fuse on its own.

Mechans,

He suggested that perhaps something happened in shipping to cause the fuse to burn out!!
Aewhistory

You know the way I read that?.... The amp could have been damaged in shipment and when the buyer hooked up the amp and powered it on the fuse blew.

Doesn't that make more sense?

Aewhistory,

Is there a chance you shorted the speaker output terminals, with the connected speaker wire terminations, of the channel with the blown fuse?

Before you install the new fuse and try to power up the amp again make sure the speaker output terminals are not shorted.

Finally, I think what bothers me the most is that the channel never made a peep. It wasn't like there was this very brief sounds and the fuse blew cutting the sound out, I mean it was like my speaker was hooked up to nothing.

It appears you hooked up the left speaker first. Just guessing when you powered up the amp the right channel fuse blew.

I happened to have one speaker readily on hand that wasn't already hooked up, so I hooked it up to the left channel. Sounded peachy.

>>>>>>>>>>>>>>>

Still, the fuses aren't blowing when I turn the amp on or anything, there is just no sound. I know this amp is old, but I don't see any VISUAL evidence of a problem.

I went and put the left channel fuse in the right holder and tried turning the amp on again. Still no sound. I went and put the fuse back in the left channel and moved speaker wire back to left to make sure that the fuse was still good. Left channel sounded just fine... Again. So this time I left the left channel fuse and put in my own fuse with same ratings. Nothing. Tried raising volume. Nothing.

Sometimes a shorted component will clear itself under power and become an open, causing a circuit to be open..... Just guessing that is what happened.

Oh, he told me I should file the insurance claim.... AFAIK, doesn't the sender have to file this?
08-30-12: Aewhistory

I believe so..... The seller did insure the amp, right?

Packaging: the amp was wrapped in one very thin layer of bubble wrap and then put in a box stuffed with shredded paper. Since the box was only a bit larger than the amp itself--about 1" extra on most sides--there wasn't much room for packing material to begin with. Sadly, the shipper didn't even really stuff the box with shredded paper, so the amp could easily moved inside. So it is entirely possible this amp was damaged in shipping.

The box looked like a big ball of tape. I'm not kidding. Every inch was taped, sometimes three, four, five times over. The top of the box had caved in some during shipping, but the massive amount of tape kept it all together, so to speak. I'll take another, closer look later tonite.

As for the amp, I haven't noticed anything that I would call shipping damage. There are plenty of signs of aging, but no bent fins, dented structure, visibly broken internal parts, etc. What I DID find, though, was that is was readily apparent that this amp has had many hands inside it before. It is missing some of the screws for the top case and those that are there are different (and visibly different ages as well).

No outside physical damage on the amp? I bet the the shipper will look for outside physical damage.....

If I could ask, how much money are you into this amp?

I'm a little puzzled by your description of a shorted component and clearing itself. It isn't that I disagree or anything, I merely don't think I understand. Would you mind elaborating?
08-30-12: Aewhistory

Aewhistory,

By clearing itself I mean the shorted component burned itself free, open. The component is shot. Or a shorted item may have caused a resistor to blow. Again causing an open circuit to exist.

You say you got around $120 in the amp. Does that include shipping?
The way PayPal works if you win a dispute resolution you eat shipping both ways.....

You say the seller has stopped communicating with you. That is a shame.

I was going suggest you take the amp to a repair shop and get an estimate on the damage.
Most sellers will work with the buyer in paying for a repair. It could be something simple you know....

Didn't you say you build/ repair computers?

I assume you have a multimeter. I posted a Link in my last post of the amp. Lots of info there....
.

I have blown a fuse--in fact I've only ever done it once and that was almost 15 years ago--but doesn't a fuse blowing make a little sound? Or am I just off my rocker? (the answer to that question is probably yes, but you know what I mean).

Short answer, no.... You would not hear anything....

Simple solution? Take the amp to a service repair shop.
The problem could be something simple to repair.....
