Dial strings are more likely to slip than bind. Inspect the string while turning the tuning knob and look for slip. If that’s what’s happening, applying a small amount of resin can remedy the problem.
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?

This is from the manuel. It has a good pic and tips on how to do it, in the repairmans notes.. MR73 http://thetubestore.com/lib/thetubestore/schematics/McIntosh/McIntosh-MR73-Service-Manual-Schematic.... Regards |
Thanks for the responses. cleeds- The string is indeed slipping. Turning the dial to the right and helping the cable along, the dial is now moving freely. Couldn't determine where the slipping was occurring. Moving the dial past 91 reminded me that there just isn't anything of substance left! oldhvymec-thanks for the schematic. I have the tubed 71, but likely there are many similar things( like cable restringing) I'm glad we have a few options for repair here in So Cal. Even though I repaired photocopiers in the 80's, I now wouldn't have the patience to even disassemble the Mac and attempt such a feat. I'd have left over screws and missing parts to account for! |
