Amph or cabinet???

[riverrick]

I have a Marshall JVM 410H amph head which I bought in 2009. A few months back I was noticing that the amph was cutting out every so often. Took to my local guitar store they replaced all my tubes. Brought it home and a few days later the same thing was happening. So went back got my $$$ back. Took it to another place, again said tubes were bad. Brought it home and again...cutting out. So went back to 2nd guy and he refunded my $$$. So shelved the Marshall head. Bought a Peavey Valve King II Micro. And yesterday noticed the same thing AGAIN happening!!! I've got the head connected to a Marshall MG 412B cabinet. Now I'm wondering could it be something wrong with the cabinet??? A loose connection or something. I don't move the cabinet around it's been in the same place sine 2009. Any input would REALLY be appreciated.

Hmm, strange. Bad speaker cable?

Thanks for that idea Robert. Will give it a try.

Might want to check the solder joints in the cabinet to the input jack and the speaker connections inside. I've had PA cabinets that cut out because the leads to the speakers had slipped off the terminals.
Good luck, I'm sure you can find the problem.
