The model number is 4118, chassis 101. Thanks for looking that up. I pulled out a 630 schematic (I have a 630 in a cabinet that needs alot of work I wouldn't mind parting out to fix this) but I don't think the power transformer from the 630 would work, it uses 2 5U4s in parallel, whereas in this set the secondary is actually tapped in 5 places 360v-175v-0v-175v-360v, and the 5U4 hooks to the 360v, while a 6X5 goes to the 175v. There's alot of similarities between this and the early RCAs, but where it's different is in the power supply. I seem to remember seeing some early Admirals with something like this though.
