As I understand it, your replacement transformer has a 6.3V winding for the tube heaters (filaments), but no 5V winding for the rectifier 5Y3GT. Is this correct? How did you have the present transformer connected to the heaters when the radio was working?

If you can't find a suitable transformer, you can use your present one by replacing the rectifier tube with silicon rectifier diodes and leaving the 5Y3GT tube with its socket wiring unconnected. It won't light up but will at least look original

Based on the way it was wired, it was missing the 2nd 6v (12v ct) secondary marked H (Heater?) on the schematic.  The way I got around that 45 years ago when I replaced the transformer was to use the existing 6v secondary to drive the heater circuit and ground the other side of the heater.  I also had replaced the rectifier tube with solid state diodes.  I'd really like to put this back to the way it's supposed to be but will consider all options.

   

Thanks!
