Epiphone EA-600RVT Solid State amp weak output volume problem

Not to worry, I often suggest people "ball up their fist and whack" their amp.  If you want to be more official about it, use a rubber mallet - I have a couple of those by my bench too.  Certainly it won't hurt the amp.  If the amp cannot withstand a good whacking, it will never hold up to transport in the trunk of a car gig to gig.

Fist or mallet, I will hit a complete amp - in the cab - on the top and ends and front and back.  If the chassis is on the bench, I will whack the end of the chassis with my palm, no wires there.  And of course the rubber mallet can hit the ends of the chassis or the top edges or the transformer or even a flat area between parts.

it is a reasonable way to expose loose connections.  Such looseness can be a cracked solder joint, a cracked or broken copper trace, even cracked connections within components.  A lead coming loose inside a filter cap for example.

And sure, lifting an amp up a couple inches at one end and letting it drop back to the table top is not really any different from whacking, it just sends a mechanical shock through it a different direction than a mallet.  I used to make that a regular part of keyboard service, because aside from loose connections, it also sometimes exposed key contact problems.

I was not accusing anyone of amp abuse, just pointing out to all who read the thread that there is nothing wrong with whacking the amp to find out what is wrong with it.  But there are people who honestly think it is OK to just smack an amp to get it running every time, and considers it a fix.

It seems that sometimes it's easy to misinterpret the meaning of some posts. Thanks, Enzo.

Yes, I have run into the same problems quite a bit. It seems that nobody's wanting to start a band these days. I've met people who will say they want to start a band, but they're usually just all talk.
If it sounds good, USE IT!

Oh, and very glad to hear your amp is finally working, Billy!  :tu:
I expect your neighbors are really enjoying it, too. Haha
Oh, and my apologies for the way the above post turned out. Not sure what happened there.
