Hi! I recently acquired the above named radio off Ebay. I've recapped it and replaced the rubber tuner mounts that were toast. But unfortunately, the previous owner had cut the speaker wires and shipped me completely different 5 inch pm speaker??? Luckily, I have a Philco S-21 speaker sitting around from a junked radio years ago which should work according from what I found on the web that can replace the original S-7 speaker. My problem is there is 3 wires coming off the speaker/output transformer and I'm uncertain which wires go where. The wires coming off the radio seem to be correct according to the schematic. One wire is coming from the + side of C53, one wire on the + side of C56, and the final wire coming off of pin 3 of the 6F6G. The 3 wires coming from the speaker were cut right at the hole(wasn't me) on the metal cover, covering the transformer. Two wires come off the outside terminals of the transformer and the 3rd wire comes of the right side terminal on the inside of the transformer. The schematic isn't very clear to me and the wires lack any insulation, hence no color codes to follow. I read somewhere that is not a good idea to apply power to the radio without a speaker connected, so I don't want to take any chances even though I'm eager to get it going! Does anyone know where the 3 wires connect in conjunction to the 3 wires I have have coming off the radio? Any information would be greatly appreciated!!!! Thanks!!!
