I'm getting ready to start mapping out the connections for the power supply on this 77 in anticipation of a new transformer from a 76 model, and I'm looking at the schematics for both sets. Can anyone confirm that the 76 model schematic simply doesn't label lugs 1 & 2 on the transformer and begins labeling lugs at what would be lug 3 on the 77? If that makes sense, that is. The 76 schematic gives no label to the 117v line, but shows it with the switch as the primary, and the 77 schematic labels the primary lines as 1 & 2. The hookup looks identical for the part of the circuit hookup for the rectifier, choke, capacitor block, and wire-wound resistors. Am I seeing that correctly?
