I have a Rotel 1080 amp which has behaved excellently until recently, when it started blowing fuses. The dealer replaced the fuses, it ran well at the store, but blew fuses again at home. A tech came out to the house, checked it out, blew the fuses. He said the problem MIGHT be a low voltage coming into the house, like 118V. In spec, but on the low side. Does anyone have any thoughts on this?

I'd bet there's something else wrong with the 1080 that went. I had the same sort of issue with my 1090 after a power surge hit the house. I replaced the surge board in the 1090 and still had to have it looked at by a local repair place and they found a couple resistors or something that had been damaged as well that was shorting things out. Nothing that could be seen except with the trained eye, which I did not have).
My guess is there's something else that's wrong vs low voltage...Digital Audio makes me Happy.

You say the unit worked well at the shop?. For how long?. Did the shop run the unit under load (As in driving speakers)?. It's possible that there is something wrong power wise at the socket where you plug the unit in. Try using a power conditioner and plug the amp into a different socket to be safe.
It could always be what Pewter said above also. It's going to take some serious investigating here to track down the problem!!.Dan Madden :TComment

Thanks for the advice. Not knowing what a power conditioner is, I consulted Wikipaedia. What I understand is that it's some sort of combination of surge suppressor and voltage regulator. Question is: Will it accept a lowish voltage, i.e., my 118V, and output,say, 125V to the RB1080? If so, maybe that would solve the problem (if, that is, low voltage really is the problem).Comment

118 is fine and so is 110. Thats not your problem.
Didn't 1080 have this issue, this is a common problem if memory is correct.
Maybe Glen will chime in..

Had the same problem, it is caused by the 12v trigger. Not using it will solve the problem.Comment

I wasn't using the 12V trigger, so that probably isn't the problem in this case. In any event, the dealer has sent the unit back to Rotel and they are going to replace several electronic items---capacitors, resistors, etc. Your replies helped me talk in a somewhat intelligent fashion with the dealer, so thanks for the input.Comment

Not saying in this case the power was the issue , could have been might not have but
Having a good quality surge , line conditioner , voltage stabilizer is a huge value to any ones system. The worse thing you can do to electronics is give it bad or incorrect voltage. Brown outs are terrible on transformers and basically robs the life out of the components. Some more then others depending on sensitivity.
If you have HDMI anything , it's crazy how easy it will fail under less the ideal conditions.
I strongly suggest anyone who is building or owns a system to really do their homework in this topic. Why spend thousands of dollars building a beautiful system only to lose to to poor power conditions?
This is a very good place to make a wise investment. But I strongly suggest learning everything you can.Comment

Hey all,
my RB1080 died a few weeks back - the old no left channel trick!!
I am local in Melbourne and dropped it off to International Dynamics in Richmond. I explaind to them what Aussie Geoff had gone through with them personally, as I am sure many of you all have in your various... -
Hi,
I have a new RB 1080 that has blown it's one of internal fuses (the ones between the power supply and the output stage) twice for the left channel. This is my second unit, the other blew the right channel fuses. Once replaced (with 6.3Amp slow blow fuses. the amp is fine again).... -
I've owned the RB1080 since March 2004. I believe it is what is referred to as version 3-it has the dual "WBT-like" speaker binding posts.
After over a year of use (listening to classical, chamber, rock, jazz at "healthy" volumes) I lost the right channel.
A friend,... -
Hi there,
So my RB-1080 got delivered this weekend, but the seller forgot to put the power cord in the box. So while I wait for him to send me the stock cord I was just wondering if I could use a power cord from my PC to run the amp? Looks like the same socket to me.

It would appear that my Rotel RA-971 MkII does not like electrostatic speakers. I was driving it pretty hard into a DIY ESL which it had handled well before. Two fuses near the power supply blew as has happened a couple of times before, so I replaced them. Then I turned it on again and even with no...
