Hi all..I have a 1924 battery operated radio with two bad transformers ...Only one coil in each transformer is good. First...in transformers..is the inside coil the primary or secondary...Also I know that you can replace the transformer with a new one (inside the steel shell) but, I also am aware that you can use a resitor and a small cap. to do the same thing but not sure how to go about this or where to find the info...Could someone please help or direct me to where I may find info...THANK YOU...
