I'm just about finishing up rewiring and replacing all caps and resistors in a 41-221 (which I am convinced the devil himself came up with this chassis design and the rubber wires), and have two questions.
First one is on the dial string. It looks like it should be fairly straight forward, but I want to confirm. On the tuning capacitor is a single pulley with a hook in the groove of the pulley. Do you just put one end of the string around the spring, put the prong on the hook, wind it around the knob shaft once or twice, then connect to the other end of the spring? That is the only way I can see it working, but there was no straining info in the copies of the service notes I got from Chuck.
Second is, what to do with the big asbestos pad under the chassis? I'm not sure if it's glued to the bottom of the cabinet or not. Is there something you can apply to it to seal it, and leave it in place? I am replacing the Candohm with 2 large ceramics (a 5w and a 10w for the larger section). Is heat going to be an issue under the chassis?
Thanks,
