Knight KB-85

[Sam Cogley]

I know there are several KB-85 owners on here, do any of you have one that's currently taken apart? I could use some hi-res photos of the front end boards from each side. :thmbsp:

Hi Sam, I have a post on "AK" asking for a layout diagram for the PC boards for the KB-85. Sounds like you where in the same boat back in 2015. Did you resolve your PC board issue?

What kind of problems are you having with the KB85 input board? It's been a while since I had one on the bench- but I remember having all sorts of issues with resistors in the feedback loop (both the feedback resistors and the input tube cathode resistors), that were causing noise and a big gain difference between channels. I'd recommend checking those, to see if they're off value or intermittent.

Regards,
Gordon.
