I bought a used DrBass Rx210 on eBay recently, and when I opened up the box I immediately noticed something rolling around in the bottom of the cabinet. I emailed Marc immediately and he was very helpful, but by the time I figured out how to open the cabinet and discover that it was a Capacitor that had fallen out, weekend was upon us and I believe he only checks and replies to the DrBass email address during the work week. So, the capacitor reads "Dayton MPR 5.6uF 250v 5% Audio Grade." I don't really have much experience with electronics but I was hoping this is something that can be easily reinserted into it's original position within the cabinet if I only knew where to put it, because I'd rather not ship the amp back to DrBass or pay a local amp technician who more than likely has no experience with DrBass cabinets. Does anyone have any advice on what to do? For the record, I had been playing the amp before I found out what it was inside and it worked (as far as I could tell) normally. Since I found out it is a fairly important piece I have stopped using the cabinet. Would using it without this capacitor damage the cabinet in any way? Could I go back to using it in the mean time? Thanks for any help.
