AnyFM tuner mechanics out there?


Perhaps  can shed some light on what's going on with my Mac MR 71?

Recently had the tuning dial cable restrung. Now I can't rotate the tuning dial to the right past 91.5! I can turn the dial all the way left. I popped the cover to inspect the cable, and don't see any obvious binding. For now I'm at least stuck with all the public stations I listen to.



Any idea what could cause the tuning mechanism to bind as described?

I took a look at the wheel, and there are 2 springs. 1 is extended and the 2nd, not so much.
@tablejockey  This is a pretty common setup. I suspect as you work it back and forth, the spring tension will equalize and it should be fine.
There is a spring located on the actual wheel that is on the tuning capacitor shaft. Is it loose or does it have tension on it? It should be stretched out to be about 3/4 of the distance between totally loose and the limits imposed by the wheel. Take a look. You may have to tighten it up slightly.

Sounds to me like whoever did the restringing didn't fully test it out. Restringing is a bit of an art.
