Any tips on refurbishing an awesome-sounding but beat up Ampeg 810 cab? I picked one up super cheap on CL and finally got a chance to sit down and go over it. I played it before the purchase, and the thing sounds amazing. That said, it needs a lot of TLC. It has no Tolex and the bottom area where the casters are is completely busted up. The hardware is pretty worn out, too, with the exception of the top handle. So...a few questions: 1. Is this a doable project, or am I in for a really tough chore? 2. How do I go about determining the age and model? The jack plate on the back seems to have been replaced at some point, but I'm not sure if that's the case of not. I'm not super familiar with Ampeg cabs. 3. What are the recessed seat things on the top surface called and where can I get replacements? 4. Is it possible or advised to put a "Deep D" handle on the sides? It seems like those would be really helpful if installing them isn't too much of a pain (not sure if any braces run through those spots. Here's a photo of one of the speakers. Can anyone help identify this cab? Let the fun begin!
