One is just like yours and the other is a Silvertone Powr-shiftr, their spelling.
Look in N/A for Spiegel model A and under Sears for 138****, don't remember the exact number, but there's several versions for different radios and different power inputs.
The "A" supply has large value Electrolytics, at 3 volts, that are really large.
It also has a choke and bridge rectifier.
The older model uses a 6J5 as a B+ rectifier.

The Spiegel number is Model P compact.
The Sears numbers are under Power-Shiftr.
IIRC, there's a schematic inside the cover of unit.
