I was just playing my stangray and thinking holy crap this thing sounds amazing...the best iv really had it sounding.
Started with the brake lite on 2 clicks, and dialled in 1 click...all sounding great. Then I took it wide open for about a minute...then crackle, sizzle,pop....now nothing. All power tubes light up bright red, but no sound.
this sucks.

Check your rectifier tube...also, I hope those power tubes were glowing orange, and not red?!

a blown fuse? if yes check the power tubes also...even if they light up they could be damaged

Sounds like power tubes to me. But you may need new fuse, rec and power tubes too.
Once something burns up, it can take other things with it.

Probably the fuse. Always have spares around.

Looks like it was a fuse. The 1/2 amp one
Now do I have to get a slow blow fuse? Do you guys use slow low on all of the fuses?

Slow blow is the way to go.

Slow blow is the way to go. For both the 1/2 amp and 3 amp???

Fast acting fuses are generally used in solid state amps , stereo and medical equipment etc. because the chips and tiny resistors and capacitors will fry easily so they need the power interrupted very quickly . In a tube amp there will be occasional bumps in voltage that won't harm anything so you want a fuse that won't blow unnecessarily.

This thread reminded me that I need to go buy some fuses and throw in my gig box! Many years ago (about 1994) I had a fuse blow at a gig in my 1969 Deluxe Reverb. My bass players said "wrap a foil gum wrapper around the blown fuse", so I did and it got me through the gig and it NEVER crossed my mind again...... Then about 2006 I traded that old Deluxe, about 3 weeks later I received an email from the guy I traded with asking me how long I had been running the amp with foil wrapper around the fuse?? I had to tell him the truth, I said "about 2 weeks"

Tried to replace the fuse and this time it popped within 5 minutes. I'm gonna take it to my tech tommorrow and see if it's a power tube. I also don't remember the rectifier tube looking that hot but I never really paid attention.

Yeah I think the rectifier tube was gone and took the power tubes with it. Did a rectifier tube and power tube swap and everything seems good for now.
Anyone know who makes the el84's for mesa boogie? That's the ones I got in it right now.

Glad to hear it seems sorted. This thread makes me realize I need to keep a couple rectifiers on hand too. Keith

My Stang Ray did that twice - both at big gigs. the first time lost volume over about 60 seconds, them fizzled and stayed dead. Took it to a tech where it came back on. The second time it just died like someone had powered it off, but came back to life after I got it home from the gig. Tried a local certified tech the first time, sent it back to Dr Z the 2nd time. Both times "no problem found." Kind of a bummer. My Stang Ray head hasn't gone out on a gig since, which is a drag because it sounds so great. I do use the 2x12 cab all the time. Love it.

I take a solid state rectifier, power tubes, preamp tubes, & fuses with me whenever I gig. Had to use rect. once, preamp tube once, power tubes once so far. A spare head also depending on gig.(should always but I'm sometimes lazy)

Had this happen with my new Ray(7 months old). The amp sounded SO GREAT right before pop goes the fuse. Replaced the fuse and watched the fireworks inside my rect tube...blown fuse #2 just before I could shut her down. New rect tube and power tubes....started playing again...then my EF86 went micro...lol. They don't make tubes like they use to! The good thing is the Doc does make amps "kinda" like they use to....only better!
Waiting for Z to start making tubes....I'd buy em up!

A couple ideas. I always make sure I plug into a really good surge protector. If you want to take it to the next step, use a power conditioner - to make sure your rig is receiving clean power at a steady voltage. A close friend of mine owns one of the 2 or 3 largest commercial sound companies in the U.S. (he is also a killin' guitar player that has done hundreds of commercial sessions); he laughs at the close attention guys pay to NOS tubes, etc - when the #1 effect on an amp's sound and tone is clean power and steady voltage......at least that's the way he sees it in his 40 years of doing sound for bands like Journey, SRV, King Crimson, etc.
Next, when I e-mailed back/forth with the Doctor about fuses, he said Fast Blo -- period.
And when you gig - ALWAYS carry spare fuses, recto, power and pre tubes. That's Chapter 1 in The Gigging Man's bible.
