Issue w/Ashdown ABM500

[LarryR]

Before I run her into the shop for repair, maybe someone has some ideas for me to try.
ISSUE: Past 10 hours of playing it, the Amp has been cutting out for a second or two only. Usually when I'm hitting the strings hard. When it kicks back in, I'm getting full power. Today I turned her on. No sound at all. Using the scientfic method I tapped (mildly banged) the right rear of the amp where the transformer resides. Amp goes on to full power. Eventually it cuts out. Seems like a "short" somewhere. Any advice for me, with the caveat that I'm not technical enough to be fiddling wtih transformers. Thanks in advance gents.

Try banging it on the side, that worked on a tv I once had.

Seriously though, there may be a protection circuit kicking in earlier than it's supposed or to protect itself from some other problem. Perhaps weak caps that can't recharge fast enough. Sounds like it's tech time.

Sure it's not just a "short!?" kidding. Thank you for your input will33.

It's amp tech time.
