[Music in a bottle]

Thanks for the advice. you guys are awesome! Texas, yes they are 2 model 14's bolted together. The inside build quality reminds me of a ColIin's radio. There is no power switch on the model 15 and so I have it plugged into the preamp, switched receptacle. It actually wasn't a thump at all, but rather a buzz of electrical sound as the in rushing current hit the caps! The search has begun for replacements, and I located a guy who rebuilds model 15's and 16's only, so he might be able to line me up with these unusual caps. Will try to put up some pictures of the whole remodel, as this stuff fascinates me!
