Spartan JR (410) Audio output and Choke replacement
11/1/2009 11:42:55 AMRuss
I have a Spartan Jr (410) the cabinet is finished and looks great. The radio is restored. I am using two 45s in place of the 183s, with the correct fil voltage. My problem is that the field coil - output transformer - speaker assembly is missing.

I see on the schematic that the field coil/choke is 2300 ohms. Is that a restance value - very high. I also need a recomendation on a OT for the PP 45s. All I have been able to find is the high wattage stuff.

Thanks

2300 is the resistance of the field coil. You can use a resistor to replace that. For an audio output transformer try " Play Things Of The Past " for a vintage transformer for 45 push pull.
