My pleasure! The Kenwood has been playing all day, and it's wonderful. It always was wonderful, but now it's more so! I need to be a bit careful about keeping the bearing oiled, but I have a friend who's handy with machining and metal work, and I'm sure we can come up with something that will keep the oil in!
If you want a really huge mod for the Kenwood, then bypass the crude PSU regulation on the circuit board and implement something better engineered. All you need is a finely regulated 23.4v DC supply, and the skills to unsolder a couple of components and to attach two wires. The Service Manual here on VE has the circuit schematics, and it's easy to work out what needs to go where. I use a Paul Hynes Design PSU (see http://www.paulhynesdesign.com
) but it's not difficult to knock up something that's way better than what Kenwood used originally. A beefier and properly regulated PSU does lift the KD-770D's performance by quite some margin, in exactly the same way as it would a Technics SL-1200's.
