Negative Feedback Bogen CHB100

blowingots · 9th August 2006, 01:50 AM

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?

Thanks

a schematic and/or some pics might be nice... saves us the hassle of trying to find them online..

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

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.
