Hope you don't mind me jumping in here but if you are able could measure the primary resistance of your Range 1 RF coil? I have a 37-660 on my bench and believe my primary was bad. Schematic calls for 130 ohm and I measured less than 100. The "Philco" tape was across the outer windings under the wax (wave wound). BTW, the primary is cloth covered single strand #38 (I think). The cloth is missing in several layers. Multi strand is used for connection to the wafers.
