I don't have my K2 yetÂ…but should have it in about a week..depending on options. I noticed in the schematic that the side-tone output(U10B pre-amp) looks to be connected as a secondary input to AF-amp(U9 LM380). This makes me assume that side-tone volume is not fixed, but instead changes along with, and is a percentage of AF volume. If that is true, its a setup that I don't prefer.
My (off-the top of my head) solution would be to splice in a 2N3904 on the output of U10B, and then move that output over to AF-OUT. That way, I always have a fixed side-tone volume, no mater what the AF volume is set at. Has anyone else done something like this already?
