101 belts (?)

[Stewart D. Lyon]

I have the manuals for the SB-100, -101, & -102.

The SB-100 shows dial cord for the two driver caps and the loading
capacitor. Advantage: positive control; doesn't load the loading cap
bearing. Disadvantage: almost impossible to sync the driver caps.

The SB-101 has the 3 belts: Advantage: easy to sync up driver caps.
Disadvantage: control a little mushy, puts a heavy sidewise load on the
loading cap bearing.

The SB-102 has belts for the driver caps and dial cord for the loading
control.  After who knows how many rigs, they finally got it right.

On my SB-101, I use dial cords for all three capacitors and solve the
syncing problem by cutting the driver shaft between the two pullys and
reconnecting with a shaft coupler. For you puriests, the shaft was from a
junk rig.
