I just bought a set of belts on ebay for $2.98 postage paid. Search for
"HW belts" on ebay.

Subject: SB-102 drive belts

Working on an SB-102 which has dial cords and springs to drive the 
preselector capacitors
Problem is one cord was so tight it would cause the capacitor to distort

mechanically near the high end of the tuning range causing scratch sound
in 
receive while tuning and jumpy power output on transmit tuning.
As the plates meshed more and the tension relaxed everything was fine.
Did some of the SB's come out with string drive?  This is a very high sn
ove 
15k. I thought they used rubber belts (O rings). The manual I have shows
the 
belts.
I'm thinking of converting this to belts because lengthening that cord
and 
re-stringing it is proving to be a real challenge to my sore fingers.
Does anyone have a size recommendation for the O rings?
Thanks in advance
