the 10M small enough to give good range a quick calculation showed +/-1mv trim
yes, you are correct about the max offset. In my testing with various ones I found the offset to be 1-2mV so I spec'd 10M for max control (range). However to cover for worst case 3.3M would work very well and still have good adjustment.
i checked out your schematics altium is such a nice program
yes it's great. That's what I use at work, I'm good with it and can do a lot of stuff faster. The only problem is in the DIY world compatibility is a bit of an issue. For single and two layer boards Eagle is very DIY friendly.... you should see the reaction of the older guys at work when I pull up a layout in Eagle... they sort of snicker... wonder what it is and think it's a toy... jokes on them though, still a very powerful program if you need simple schematic capture and layout.

btw, very nice enclosure. We're getting very spoiled with all this x0xb0x stuff. It has to be the coolest diy thing ever.

Thanks and agreed. Aren't you using the same style case? I thought I saw a pic of the BCbox in an FPE enclosure.. I am thinking about a all black one if there will be a 2nd run.

WRT DC offset: what is a starting point on the 50K trimmer? should I start at short and go up from there or somewhere in the middle?

yes, I made one prototype a few months ago and will be doing a run in the future. Only works with my kits though with the custom mainboard...

start in the middle.
