Power Amp worries

[RemoWilliams]

So yeah, what does it mean when your playing your amp and the makings a popping sound thru the speaker cab, and the power amp powers down? I know this can't be good, but hopfully nothing too drastic. Its a Rivera Hammer 120 power amp. Let the worry begin.

is your cab the right impedence for the amp?

 

[RemoWilliams]

Yeah, I had both sides set to 4 ohms out to the Mesa cab in stereo. Unless I'm a dumbass, which I have been know to be, and did something wrong on that end.

 

[Wolfeman]

if the amp is stereo, 4 ohms on each output, then both sides on the cab would need to be 4 ohms also. Most guitar cabs are 8 per side, and when running all four speakers you get 16ohms. read the back of the cab and tell me what it says.....

Alrighty. Its a Mesa Standard Oversized cab. http://i5.photobucket.com/albums/y170/johnzorn/back2.jpg hopfully I didn't fuck up the easiet part. Hopfully it just blew a fuse or something.

 

[Wolfeman]

looks like you hooked it up ok, 4ohms per side.... Don't know what to tell ya....

 

[RemoWilliams]

Thats good to know. With tube amps, I guess its hard to tell. Maybe a tube decided to die or something. I supposed I should have it looked at and see whats up. Thanks for you help.

if it blew a fuse, it probably wouldnt work anymore until the fuse is replaced

as far as I know, volume-loss from a tube-poweramp is often a tube-problem. this would mean a new set of powertubes

but if you have a qualified tech have a look at it, he should be able to tell you what the problem is

 

[RemoWilliams]

Yeah, I'm really hoping its just tubes or maybe small internal problem (crossing fingers its not the transformer or what not). I'm a call around and see if I can find someone to look at it.

hmm, last time I read a comment from a tech about output-transformers (I think it was a guy from some custom-amp-company) I think he said something like "either its broken, or its working, something in between is VERY rare"

hope you get it fixed soon!
