Hi there. Proud owner of a DT25 1x12 combo alongside with a HD500. Been using POD's for years, love them!

I have a small problem with the DT25. Something has come undone inside the chassis and is rattling around inside when I move it. Sounds metallic, like a nut or something. Amp is working perfectly, all knobs and switches secure on top panel so confident its nothing 'important.'

I'm wondering if anyone here has pulled their amp apart to check the tubes or just to have a look inside the chassis. What are the steps in taking the chassis out to have a look? Everything seems pretty tight around the cabinet and chassis so want to make sure I follow the correct order of removing screws before going ahead to discover what this mysterious piece is that's come loose.

Instructions with photos, link to youtube video (I've checked but haven't found anything yet) or a simple step by step procedure would be valuable.

Thanks in advance

Marty
