Some of the wiring around the choke area is not matching the circuit diagram.

Hi Frank
Looking at some of the other photos of 54s they appear to have a choke mounted on the loudspeaker too. The schematic doesn't appear to indicate the use of an energised speaker. I wonder if the speaker in your 54 is not in fact correct?
