Hopefully, someone may be able to tell me what may be wrong with my amplifier.

I had it on, and was listening to music, and then suddenly it just died, and won't switch on again.

Sounds like a fuse doesn't it? Is this easily fixable?

It does sound like it could be a fuse. Does the manual talk about them? They are normally on the back panel near the power. If it is a fuse remember they normally do not blow without a reason so there may be something else wrong.

Uh...er...manual? Did ANY of you nOrh SE9 owners actually GET a manual??

HappyMan,

If it won't hurt the amp, try removing one tube at a time and see if it will turn on. If not replace it and try another tube. If you get done with all the tubes and it still won't work the tubes are good and not the problem. (Obvious, I know, but wanted to say it anyway.)

The fuse might be right on the back of the unit next to the IEC inlet. just unscrew it and remove the holder. The fuse will most likely come out with the holder. To check a fuse you need either a multimeter, or some wire to hook to both ends of a battery and a small buld from a flashlight. DO NOT trust your eyes to verify if it is bad. I have seen a great many fuses blow and they looked perfect to my eyes, but were totally open on a multimeter.

send it back to Norh.

Thanks Sov, but it's not the tubes, because I have tried a spare set of tubes that I had packed away.

No manual.

But it sure did sound great while it was working.

Let me find a screw driver, and I'll take a look at the fuse. I actually have two SE9's, so maybe I'll try switching the fuses around. Wish me luck.

I'd definitely recommend contacting Michael Barnes. I had to put my SE9 in temporary storage while decorating over the summer. When I got around to unboxing it and setting it up again there was distortion in one channel. I did the obvious checks and sought advice on the nOrh forum at audiocircles.com. Eventually MB sent me a new amp since it was less than a year old. The new one works fine. (I had to pay the import duty, UPS 'brokerage' fee, etc as I live in the UK, though.)

It's a great component when it's working.

Hmmm... The fuse was indeed blown, and I replaced it. But now when I turn it on, the rectifier tube glows bright blue, and makes a buzzing sound.

I've never pulled the power cord so quickly before.

Michael Barnes is helping me out. Thanks for your help guys.

YIKES!! It almost sounds like there's some kind of short or something in your rectifier tube. Let us know what happens.

 

[HappymaN]

Turns out my rectifier tube went dead, and caused the fuse to blow.

All I need is a new fuse, and a new Sovtek 5AR4 rectifier, and I'll be alright.

How about getting a Mullard or other NOS 5AR4. It's awesome.

Ouch, NOS and student don't mix.
