Truetone D724 power xformer replacement?
#1

I have a Western Auto Truetone D724 (1938) Riders 11-1 with a bad transformer. I was googling trying to find info and came across a thread in the Antique radio Forum and found a thread on the d724 with a bad xformer. I bought a Hammond replacement xformer a 272DX with a 6.3fil and lamps and 5v for the 80 filament. Now my problem the print shows a winding on the secondary (center winding) going to the 80 plates and a center tap going to the choke and filter cap. Did I get the wrong xformer? What am I missing?
