[Boatanchors] Re John Brooks Needs Help

[Duane Fischer, W8DBF]

I am helping a
friend repair his RCA console 78 player and the magnet
structure on the field coil speaker is getting pretty
warm, maybe 120F.  Resistance of the field coil is
in-spec at 1100 ohms.  It is, of course, the choke for
the power supply and does carry a fair amount of
current, but my question is how warm are these things
supposed to get?

Thanks,
John
