what is the difference between this cb version circuit and a non cb thank you

means they used the "Composite Board" of the 6000 Di Pro SL. The 6000 (featuring Auto-Trac) had revisions that moved it to the final stage of design and eventually the 5900 Di Pro SL's "advanced" to that revision.

The earliest 5900 Di Pro SL had the bolt & nut connection that secured the middle rod to the upper rod, and it also had the Signal Balance control on the front side of the control housing (the side the coil connector is on). Running design changes (revisions) finally resulted in the "CB" versions that essentially functioned like the 6000 Di Pro SL, with the obvious exception of one having Auto-Trac and the other having manual Ground Balance.

As for actual, in-the-field performance, you can't really tell much difference between the earlier 5900 Di Pro SL and the last revision. The 5900 Di Pro SL was the one I favored over the auto-tracking version and it was my main-use using until he XLT was released in the spring of '94. Eventually, I also took up the 6000 Pro XL because it was packaged in the smaller housing and used the drop-in 8-AA battery tray like the XLT and Classic SL series. I always wished they would have produced the smaller-housed 5900 model with manual GB as I favor manual control.

So, all the "CB" really means is that the manually GB'ed version was brought up to the same basic circuit board as the auto-tracking model.
