Orange AD200 and Matamp 2x12

[umcoo]

So there I am, rocking away at practice with an AD200B and the Matamp 2x12. The head is moving around the top of the cab a few inches and I pull it back everytime it gets too close to the edge.

Mid-song and it stops making any noise...not a whistle. Everything still turned on, lights on, valves glowing as they should. No flashes, no smoke, no funny smells.

Changed leads, bass is passive and worked through different amps.

Any thoughts? I'm thinking the vibrations maybe loosened something? Good job it was the last song of the practice!

Thanks for any help you guys can offer

Jeff makes MAtamp cabs so they stop working if you insult them by plugging in an Orange. Phone him and ask him what he thnks of your amp.

Jees, it vibrates an AD200b?! How loud are you practicing?!

Hmm, not sure. Tried another cab?

[umcoo]

Don't have another cab to try I'm afraid. Would a 2x12 just stop working all of a sudden? If I blew a speaker, wouldn't one go first...not both at the same time?

Wasn't incredibly loud at practice...gain on noon and master on about 9-10 oclock. Used a Big Muff too and that's what was making the vibration happen. I thought the battery had gone in the muff at first so just went bass to amp, but still nothing.

I'm rather puzzled!

[Colledge]

if the speakers are wired in series then one going would cause both of them to cut out.... but you would probably notice a speaker blowing, also if that happened it would present no load to the amp so could quite possibly make the amp go pop, so doubt its a cab problem.

[umcoo]

Ok, back at home now. When I take it out of standby, there is a very, very slight hum which is normal for the amp. But still nothing...

get to another cab somehow if poss - elimination

I thought I'd bump this as I've just picked the amp up from Promenade Music in Morecambe. It was the Orange at fault...dodgy resistor apparently. All is well now though...God, I've missed it!

Cheers for all the suggestions.
