Well, I thought I had a use for my junker T-4XB the other day when I removed the reduction drive from its RF TUNE control to transplant into my project R-4B's PRESELECTOR control (whose reduction drive has snuffed it). I made hasty assumptions about wanting to keep common parts in manufacturing stock that have not panned out in this case: not only does the offset differ substantially (such that the pointer can't be mounted to the outer shaft), but the ratios are also different!
Does anybody have an extra receiver PRESELECTOR reduction control or a junker receiver that they'd be willing to sell me? I'm getting that sinking feeling that the TR-3 I sold last month probably has the correct ratio, but I'll wait for someone who has measured it to chime in with that. Otherwise, the chassis looks splendid! This R-4B is definitely NOT a junker and deserves to be refurbed. 73, Steve Wedge, W1ES/4 "Just so the wealth of the country, its capital, its credit, must be saved from the predatory poor as well as the predatory rich, but above all from the predatory politician." - James Jerome Hill All my computers have my signature with various pearls of wisdom appended thereto.
