I've finally pulled the first KR-6160 out of the "to do" stack and started the restoration. I'll share some of what's going on here and ask for some help along the way. After it's done and working, I'll post the results and the BOM for a recap as well as a more-thorough restoration. This unit sounds pretty great as it is, but it started acting flaky and I took it off the shelf for later restoration. That time has arrived.
