Hi all,
I am restoring a 4 band 16X, later version cabinet. The tuning mechanism needs to be restrung and I would like some info on how the string runs. The tuning mechanism is of the type that has a Vernier reduction drive, a double pulley on the right side of the assembly, and a large pulley on the dial display mounted to the capacitor shaft. It is not of the type that you pull out or push in to change the rate ratio. It does not have any O-rings as some do. This radio Vernier drive has a large outer shaft for coarse adjustments and a smaller inner shaft for fine adjustment. I also am assuming that there are no belts involved with this unit drive as the only hint of what WAS there is a piece of rather large dial cord. Another interesting point is that the large pulley with the dial mounted on the capacitor shaft has teeth in a row around the inner surface of the pulley. It does not have the usual hooks that you would hook a spring to from the dial cord. How does THAT work?
Thanks for any help.
