Ok, all the talk here and on another board many of us frequent about a potential fire hazard with the PE 250 Watt amp (or the MCM amp, which apparently is exactly the same) has begun to concern me. What's the deal? Can I stuff a small sealed enclosure to the max with polyfil and put that amp in there with the polyfil touching everything without worrying about starting a fire? Would a safe solution be to put a layer of fiberglass insulation between the amp and the rest of the box (just friction fit in in the box or maybe even staple it to the back wall) so that the polyfil never touches the amp? By the way, did your amp have different binding posts on the front? There's no holes in mine to use banana plugs.
