Green Bean/TS question

[DutchMF]

Been studying the Green Bean schematic, and after comparing to a TS schematic on GEOFEX.com (http://www.geofex.com/article_folders/tstech/tsxtech2.gif) I noticed a difference that I don't understand: In the Green Bean schematic, R6 is connected to C4 on one side and to VB on the other. In the schematic on GEOFEX, the equivalent resistor is connected to a 47n capacitor (like C4 in the GB) and Ground! That is quite the difference....... Any insights anyone?

Vb and ground are both ground in AC terms. In fact, you could tie that point to Vc since Vc is also ground in AC terms. Weird, huh.

Weird is indeed the right term for this....... Can't really get the old brain around this , but thanks for the reply. I've looked up some other 'Screamer schematics and they all tie that point to Vb... Back to the books!
