[Boatanchors] BC-348 Output Impedance

What are the output IMPEDANCES (speaker) of the audio transfomer in the 
BC-348 ???

This is a BC-348Q with a 6K6 in the audio output and the audio output 
transformer and choke in one assembly.

The secundary winding of the audio transformer offers a ''HI'' and ''LOW'' 
connection and the DC RESISTANCE measures 15 Ohms and 145 Ohms respectively 
and it looks like even the ''LOW'' connection, which is wired to the 
earphone jacks,is not a good match for an 8 or 4 Ohm impedance speaker and a 
different output transformer may be in order.

Does anybody know ???
