The phono changer is a model D-10.

The speaker is PM type speaker, 3-4 ohms impedance. The audio output transformer is mounted to the rear apron of the chassis, to the right, as you face the chassis rear. Just to the right of the power cord entrance grommet. The primary connects to the output plate, pin 3 and the other end ties to the junction of R100 and R101.
One transformer secondary lead is grounded to the chassis and the other lead went to the speaker. The other speaker voice coil wire also came back to the same ground point as the secondary lead.
The transformer part number is 32-8242-3. It has a primary winding D.C. resistance (not impedance) of 500 ohms and the secondary D.C. resistance (not impedance) is 10 ohms. A universal output transformer sold by Antique Electronic Supply should work fine.
