GE Super Radio III Tuner Re-Thread?
Hi -
Does anyone have any pictures or diagrams of how to re-thread the GE Super Radio III vernier? The Service Manual doesn't discuss it. I knocked mine loose while fixing my radio. I had a problem last year at this time where after a half hour of use, the radio would slowly tune tself across the band like an invisible hand was turning the dial. I tried to diagnose it, but the problem went away and didn't return after hit the tuning pot at R2 with freeze spray. I was OK for about a year, until it re-occurred this summer. I hit R2 with the freeze spray again, and the problem would only go away momentarily. I looked at the bottom of the circuit board and it appeared quite dirty with flux. I theorized that in humid weather the rosin was affecting the circuit. I cleaned the PCB around R2, accidentally knocking off the tuning wheel. Now the problem seems fixed but I can't get everything back together as I didn't take notes, never intending to remove the tuning wheel and thread. I think the string threads around spools 1,2,3,Loop Capstan Twice?,4,5 and then I can't quite figure out how to thread from 5 to the spring or hook on the wheel and from the spring or hook eventually to spool 6. (ASCII art facing front of radio) 1 ------------------ Vernier ----------------------------- 2 | 5 | 6 ------------- Spring \ 3 Wheel "D" slot at R2 \ | Hook \ Capstan Loops? \ | -----------4 I'd be grateful if anyone with a GE Super Radio III and a hand mirror could describe or show how to re-thread the vernier through the spools, capstan, and tuning wheel.

I'm sure someone had it on a webpage at some point, because I'm sure I saw it. The obvious place to check first is David Moison's GE Superradio FAQ, at http://mysite.verizon.net/vze20h45/r.../gesr_faq.html There are various things there about fixing the calibration, but I see nothing after a short glance about stringing the dial. It does link to a page that has the service manual online, for others who might want it. I also have this page http://www.geocities.com/rbrucecarter/sr3.htm bookmarked, but while it might be useful to owners of the radio, nothing about stringing the dial. I thought it must have been discussed in this newsgroup, but a quick search using "ge superradio string", which seems like useful terms, doesn't show anything.
