Glen -

Have no fear of that - Stanley is an antique radio collector (remember that 
his original message stated the period in which the 540A was in 
production). He was unable to find any information about the speaker in any 
of the usual antique radio schematic repositories (Rider, Beitman, Sams) 
and so was asking on the list.

I've been in many stations that had an antique radio in the lobby, but none 
with a '20s battery set suitable for use with a 540A. :)
