Congratulations K; did good! The speakers are
Oxfords (scroll down) and the two caps fastened to the baffleboard are the crossovers for the two tweeters in the top of the baffle.
Agree; looks like something used to live in the one hole but that one multi-section can cap could have served the one power supply that feeds both amps ... who knows ... looking forward to more pics. 8)
Yeah, something's definitely up there. (really need to open this sucker up and take lotsa pics...) You can see less tarnished metal in a circle around where the old stacked cap used to mount, there's a shiny sheet metal screw through one corner of the original mounting slots and you can see that that connects on the inside to a brown circuit board and a metal-shrouded cap connects to that. I assume the circuit board is a means of connecting individual caps to cover what was once stacked...
The fact that that was done w/ at least some care gives me a bit of hope for what might be inside, but it could still be a bunch of spaghetti dead-end original wires, etc.
I figured the caps must be crossovers, since they connect in line with the speakers. Kind of cool how they enclosed the oval speakers with the chassis and left the 12s open back. So, as crossovers, do the easy to inadvertently touch crossover caps carry significant stored voltage?
Oh, and the model name (SYMPHONIC M990) and "brand" (DON NOBLE CO. INC. CHICAGO..) is all part of one long emboss-a-plastic-strip label maker tape, lol.
There's a small sticker with model and serial number in the bottom of the cabinet. Model number is 381, which matches that Tonemaster 381 on the vibroworld site that visually matches this. Interestingly, though, though the control panel and cabinet are 100% the same, the arrangement of tubes is totally different.
