Hello again. I'm having trouble figuring out whether or not a yoke now listed on eBay is in fact a reasonable substitute for the RCA 71420 yoke used in my RCA T120 mentioned above. The eBay entry calls out its listing as being a substitute for an Emerson 708130, Stancor DY-1 and/or Merit MD12. However a catalog listing for the Stancor DY-1 shows a resistance of 8.3 ohms for the horizontal windings and the schematic for the T120 calls out a resistance of 13.5 +/- 10% ohms for the 71420 yoke. Seems to me to be too big a difference for the Stancor not to load down the flyback transformer. What's right here? I'd appreciate a quick answer as this item goes out tomorrow at 9:52 am PDT. Many thanks.
