Re: New KLM367 PCB: Thanks and a debugging note

2010-04-20 by hyperjed

In looking into this further I discovered that once the MG section was working properly my own board I had LFO noise present on all the oscillators. 

This was a known problem with the original boards. The solution (which involves lifting one resistor leg, cutting one trace, and running one jumper wire) can be read about here: http://launch.groups.yahoo.com/group/PolySix/message/2125

I'm not sure if I should call this a new bug, an old bug, or just a KLM-367 bug!

Anyways, if others run into this problem you might try this solution.

I'm keeping my fingers crossed for no other errors.

Best,

Jed
