in some radios, like the philco model FT-6

the neutral wire on the speaker is connected to the chassis as is one side of the audio transformer output. grounded, in other words.

in others, like the philco model N

the neutral wire is connected directly to the audio transformer but not grounded.

anyone know a good reason to prefer one design over the other?

i did find one related post. TonyJSenior thought it wouldn't matter.
