I have a Philco 90, which I want to restore. The last technician who repaired the radio made many strange changes, including the loudspeaker, which belongs to a Philco 70. This left a 45 push-pull tube inoperative. I changed the audio transformer from single ended to a new, push-pull, universal transformer, using the case of the old one to keep the original appearance. I now must rewire the whole radio with 20 gauge, cloth wire. The problem is with wire colors. The originals are very old and I cannot distinguish their colors. Does anybody know which colors I should use for the different circuits and parts? For example, of the 4 wires coming from the speaker, which is the color connecting to both 45 plates, and which to the points "D" and "E"? Does it matter which end of the secondary connects to which end of the voice coil? If so, which are the colors? I would like to have a list of wire colors (or a color code table) for antique radio restoration. Thank you very much.
