[Shop-talk] Old AM Car Radio

[Mark]

Does anybody have a diagram of a 1950's Motorola TM8A AM car radio.  It has 
something that looks like a date code of 1955, but it is solid state and I 
don't recall that car radios were all transistor until a little later.  Mine 
has a label on it but it is torn and I can't read it.  I can tell that it is 
neg ground.  It has a warning on the label that says something like "Use 
Only XX Ohm Speaker"  and it is torn at the XX so I don't know what it says.

Thanks,

Mark
