Default SP-600 tuning backlash....

Jeff,
Thats the way any normal radio deals with back lash.
Not the SP-600, at least not mine.


Is it possible to take a couple of pictures of the gear and/or
where it mates?

I'll bet putting that SP-600 back together took a while!
The only thing worse would be an R-390 basket case.


Heh, for a true "Egad!" You should try reassembling a Collins
ART-13 auto-tune radio.

Jeff,
Useful pics will be difficult. The front panel mechanical
stuff is in layers, and much of it is hidden. If I take the
front panel off (again....), I'll give it a shot.

*Big grin* And here we go, back to the original concept of
the front panel being removed and all the parts in a coffee
can.

Although, as an intermediate step, see if you can check the
anti-backlash gear and make sure it it sprung in the correct
direction to pinch, not spread against the mating gears.
