Default Negative Feedback Bogen CHB100

Hi guys, I have a Bogen CHB-100 that I am working on. According to the schematic it has a Negative Feedback resistor of 33k. I can't find it in the amp. That is to say that there is no 33k resistor anywhere along the line that it is supposed to be attached to. For that matter there is not even a line that looks like what's on the schematic. All I want to do is change the value of that resistor but I can't find it. Anyone know anything about it?

Default Here you go

I thought someone might have done one of these amps and would know exactly what I was talking about.

Default Found it

Apparently there are at least two slightly different manufacturers schematics out there and I was looking at the one that didn't quite match my amp. Looked at a different schematic and voila I found it. Thanks anyway.

old post. there are at least two schematics out there. one, which no doubt matches the OP here, is the manufacturers. the other is a modded chb-100 by someone wanting a guitar amp.
