A while back I posted about the 'SP-600 from hell'.
After a lot of work, and some great advice, the restoration
is complete. Still a couple of small bugs to work out.

One is bad backlash in the main tuning dial. This
radio uses gears that are mounted on movable plates
that are pre-loaded with an "S" shaped spring. I've made
certain that the plates are able to move freely, and the springs
are OK. Has anyone had, and solved this problem? If
so, I'd sure like to hear from you. At this point I'm stumped.

TIA

p.s.-still looking for the main tuning and crystal phasing knobs
