How do I clean up the 3 RF Transformers in my Atwater Kent Model 40? On my last post, someone said it was ok to clean the volume control coil with Goof-Off. Is this OK for the RF Transformers as well? Also, in continuing my education, what does RF stand for? Is it radio frequency?...just a guess. Thanks! <P>------------------<BR>"I'm new at this...please don't shoot."

You can clean the coils by wiping gently with a damp cloth. Do not do anything more vigorous or you may disturb the windings & change their characteristics.<P>------------------<BR>

By damp, do you mean with water only?<P>------------------<BR>"I'm new at this...please don't shoot."

I usually use a 1-2" soft bristle paint brush. Gently brush "with" the windings.<P> Sometimes does not get all the dirt. I would rather have some minor dirt than a broken winding.<P>Welcome aboard and Good Luck!<BR>Dave<P>------------------<BR>

Yes, water. Do not use any solvents. Coil wire in this era was insulated with old-time varnish - very delicate today.<P>------------------<BR>
