You're welcome. Actually, revision B refers to the K2 PC board set; we call the
latest K2 the "rev B" K2 as a result. The manual is at revision F. All manual
revisions include the troubleshooting and signal tracing data, although we've
improved it gradually over the past couple of years.

Thanks. I hope you find the K2 easy to build and that it performs well for you.

Sure. We've had a couple of requests for this, and it's on the wish list for a
future manual update. Meanwhile, what has worked well is to get comparison data
from someone whose K2 is properly aligned and working.
