Hi,
There is a 38-2 speaker advertised on the auction site now.
https://www.ebay.com/itm/203934321227
Now let's examine the differences between the speakers.
Model 38-4 uses an H-29 speaker, the same as used in models 38-3 and 38-5.
Model 38-2 uses an H-32 speaker.
Both speakers have output transformers designed for use with push-pull 6F6G tubes.
Both have 660 ohm field coils.
I don't know why Philco lists a lower DC resistance for the output transformer primary on the 38-2 speaker when both are listed as having a primary impedance of 14,000 ohms.
It certainly looks like the H-29 and H-32 can substitute for one another.
