picked up one and have been rebuild/recapping this unit, however I have run into a bit of a problem related to the main 4-section PS cap. In particular, between two sections noted on the schematic as C48B, R71 and R73, there is a 220v out that goes to ? That's right, it shows on the schematic NO connection! And I did not see any wiring to that junction as I was rebuilding the can, and there is no loose wire laying around the chassis to connect to that junction. This unit has 2 schematics on the bottom plate with the second one glued on one edge atop the first schematic, which does show a connection for the 220v rail. In fact, there seems to be quite a bit of changes between the two schematics. I will assume that the top schematic is for the current build in which case there is no connection for the 220v rail, does that sound correct? The wiring in this one also looks like a monkey put it together, were these kits or something? Have never seen a factory build with such sloppy soldering... thanks!
