Expert electronics opinions needed: Radiola 60

[Electronic M]

How much of the new PS are you planning to use? Are you planning to replace the 80 with a 5Y3 or run both some how?

What I would do is use only the transformer from the parts set. Mark all leads (ie. line, 6.3V heater, 5V rect heater, rect plate winding and it's center tap) before harvesting the parts trans.

To start, disconnect the original rect plate winding (including center tap) on the radiola (tape over the ends so they don't short). Connect the rect plate winding from the new parts trans to the plates of the 80, and the center tap of the new trans to chassis output pin 7 (ie. where the old center tap used to connect), then connect the line input of the new trans to a variac. Meter the High dc output of the PS chassis, and if feasible the AC plate voltage on the rect tube. Report back the variac setting that gives designed DC rail voltages.
