Does The Field Coil Have A Polarity?

6/13/2011 3:56:45 PMJohnny

Zenith 12-S-266. Had to buy all the speaker parts from Alan at GN4. Got a speaker and a plug and need to wire it up. I've got all the connections figured out but I'm not sure on the field coil. Red & black original wires coming off of speaker field coil. One goes to the filament of the 5Y4 and the other is common to the screen grids of the 6V6's. But is there a polarity issue? Red to 5Y4 filament and black to 6V6's?

I think not. Earphones used to be polarized so when they were used without an output transformer, the plaate current helped the magnets inside the phones. But, nothing is going to blow up if it is polarized, and hooked up wrong, so why dontcha hook it up one way, and then the other, and leave it the way you like the sound best?

:Thanks Lewis! Ran it past the guys at the other forum also and I'm told there is no polarity on the fiels coil.

It'll only make a difference if there is an anti-bucking coil which is part of the voice coil winding which should be out of phase with respect to the field coil to minimize residual hum. Not all setups had these. Otherwise agree, which ever way sounds best.

:I don't see any evidence of that on the speaker of the schematic so I guess I'm not concerned with polarity.
Thanks codefox,

........ But is there a polarity issue? ...........

Yes. If you hook it up backwards it will play all songs from end to start and all voices as reverse speech.

Play a country song backwards, and you get your honey back, the money you lost gambling, get out of jail....ohhhh, the list goes on, and you wind up sober again.

Oh if only it were true. But a magnet is a magnet. and another induced magnet pushes or pulls away from it if it is not bound. Ergo noise, or music, or talking heads. Got sound?

This is just a theory: Maybe after operating for many years, perhaps the core would develop a bit of retained magnetism? If so, it might be a tad better to have the field coil hooked up so as to not buck the retained magnetism.

Yer got a point there, but wouldn't the residual magnetism fairly rapidly line itself with the new polarity?

Yes. This is just some more of the know-it-all nonsense that often appears on this and other forums.

Take your meds Fred, and stay kool. I'm 72, and still enjoy a little humor on this site after some of nasty remarks of the past.

At 72 you probably do need meds. Good luck and keep moving along.

It oftens seems that no matter what the topic and what the answers, someone always seems to feel that he just has to add something more, usually some miniscule detail that has no real importance, and is known by everyone. But it makes him feel important to point it out to the poor unfortunates who he is sure do not share his great knowledge.

Humor is fine and makes the world a better place. But these know-it-alls only add to the noise.

Hum will increase if polarity is reversed and the speaker has a hum bucking coil. Select field polarity for least hum. Someone mentioned this but might have been overlooked.
