Phonola cathedral radio
#2

It is 1800 ohm FIELD coil. Your voice coil is likely to be from 0.7 to 4 ohm.

Now that you don't have the speaker and probably missing your output xfmr too, just get a proper size speaker and match the transformer.

The sch is similar to Philco 20 but with A output stage so a speaker from 70 could do.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
