Finally pulled the chassis out of the cabinet. Interestingly enough, the chassis slides in and out of the cabinet on slanted wooden rails. This revealed a cramped and shallow underside filled with Areovox caps. While I'm not entirely sure what's original, Someone has definitely recapped this at some point.

Curiously some of the caps have a 1600v working voltage?
Also, note the big black unmarked rectangle in the upper left corner (Capacitor?)

Can anyone share any info on what's original? Schematics are also very helpful if anyone knows where I can find any.
Thanks all,
Zach
