I have the following speakers that I want to identify. I am hoping someone knows something about them. I want to find out the current/power ratings of the field coils:
1) Hammond Rola
AO-21055-1
6232
285114
Measured Field Coil: 0.978k
2) Jensen
F12NS-C6142
AO-21055-2-SH.3
220746
Measured Field Coil: 0.699k
3) Magnavox
Markings have worn off
There are 3 wires coming out but can't see where they attach, so no idea what they connect to.
I either get 1.902k or 5k depending on which wires I connect to
4) Telefunken
Field coil is: 1.989k
No other markings
