today i can't believe it. but my vypyr will not turn on no power at all.

It's probably the internal fuse. It seems that Peavey might have used a fuse with too low of a spec. Has anyone that has had their fuse replaced looked to see if the replacement was the same value as the original?

man i'll have to send it to be fixed. i hate to be without it.

Hi,
I had the same thing happen and I sent mine back to Peavey for repair last Wednesday and I haven't heard anything about how long it will take for repair. If anyone has any knowledge or experience on the turn around time please let us know.
Thanks.
Update the turn around time for my Vypyr 75 watt repair was 14 days. the cost to me was only $10.00 for shipping.

I've had to replace the fuse in my 120 Combo twice.

I think the Vypyrs need a pretty solid power source with little fluctations. Sharing an outlet with other devices seems to really have mine lock up more than other times. Not sure if it is related but thought I'd mention it.

Anways the fuses cost about $2.00 each
You can pick them up at some Radio Shacks, call ahead and they can check if they have them.

Let them know you're looking for a ceramic 5 Amp Fuse, 250 Volts

Here is a link for Amazon.com

I now take these with me on gigs as I have blown a fuse during a gig now.

thats what it was for mine. thinking about a 10 amp fuse this time.

I would not go over the rated value. If a spike comes through with a higher rated fuse it could blow something expensive. A better idea would be to get some kind of line conditioner. I bought a used apc battery backup (APC 1500) with bad batteries off ebay ($50). I told them to remove the batteries for shipping. When I got it I added two used (mostley good) car batteries to it (check battery water level once a week). It puts out a pure sine wave at a regulated voltage (119VAC for mine), even when the power is out it will keep going for about an hour, with my vypyr. No surges or low voltage line conditions will get through. Cheaper battery back ups put out a square wave which is not good for this application.

Do you gig with this setup? Seems to me it would be a little heavey to lug around.

No I don't gig, not that good yet, and yes that stuff is heavy it stays in the shed or goes out in the yard when I want to get loud. Power in my neighbor fluctuates some with occational flickers. I use the same setup for my computers and network. I thought it would be a good idea for the amps I have, but two batteries at 50 lbs each and that ups at 25lbs is tough to carry around even strapped to a dolly. You do what you can with what's available sometimes. I had the batteries, so all it cost me was $50 for clean power.

I had never heard that, but I guess it makes sense. My fuse blew about 2 weeks before I had a tube blow...but I think its the preamp, all the power tubes light up like normal...or will they do that whether they're blown or not?

This is my first tube amp, so I'm a little out of my element. My sound cut, so I assume it's a tube. I'm taking it to the place I bought it from Thursday.

The "light" is just the heaters for the cathodes and is not an indication of a good tube, although if the heaters are not on the tube will not work at all.
Tubes go bad mostly from being over driven with plate voltages way beyond the design spec's, but having high plate voltages is what makes the tube's characteristic tone. It's a trade off, shorter life or no tone. Guitar amp tubes can still last several years. It all depends on the hours the tube has been used and the amount of plate voltage.
When the tube goes, it goes with a surge of current that will blow the fuse and can damage other components in the tube circuit.
When operated below the max voltage, a tube can last nearly forever. I have a 20 watt tube stereo from 1952, all original, and it still works really good, and yes I run my guitar through it once in awhile. The bad news is guitar amps practicaly can't be used without going over the spec's.

Well, my Vypyr started humming so I shut it down. When I powered it back up ... totally deal (no lights).

I'm guessing it's the fuse. Would if void the guarantee if I change the fuse myself? It looks like it was a power tube failing. I'll try the fuse first. If I look at the tubes, should I see something different if a power tube is failing?

Thanks guys.
