Here are the pertinent specs:

32-7905

Primary impedance: 6000 ohms, center-tapped
Secondary impedance: 3.9 ohms
20 watts

The Hammond 1620A is a very close match - 6600 ohms to 4/8/16 ohms (you would want to use the 4 ohm output).

This transformer has screen taps that would not be used in this application - you would want to tape those leads up and leave them unused.
