I broke my amp…

[metropolis_4]

At aound check tonight I accidentally plugged the output of my amp into the 8ohm speaker output of my attenuator while the speaker was connected to the 16ohm output of the attenuator.

When I turned the amp on it started making a high pitched noise. I turned it off right away and fixed the hookups, but it’s constantly making that noise now.

Luckily I’ve got a backup to get through the night.

Oh no! Please not the vox

The Divided by 13…

Damn dude.

Hopefully just a tube or an inexpensive part.

 

[sleewell]

Oh dang that's a bummer. Sorry dude. We've all done stuff like that. Hope it's a cheap fix

Ooof I think the output transformer is cooked.

 

[Alex Kenivel]

Oof, I know that must hurt!

Fun night… while I was dealing with the stress of gear failure the MD came up and told me the tenor sax player was sick so he needed me to cover a few of his solos. So I had to improvise a few solos I’ve never played in my life. And one of them was a very specific melody I had to play note for note. Great timing…

I brought the amp home, I’m gonna swap out tubes tomorrow and hope I get lucky. Fingers crossed

What attenuator, does it have a solid state power amp?
Did you plug the output of your tube amp into the output of a solid state power amp?

I'm thinking the failure was more likely due to something else.

If you plugged amp 8 ohm out -> 8 ohm in on the attenuator, then you'd have a correct load on the amp. Whatever it does to allow impedance change at the output (transformer or separate poweramp) should not matter to the Vox.

Even if you plugged amp 16 ohm out -> 8 ohm load the impedance mismatch should not be a huge problem afaik.

Hope it's just a bad tube or something.
