    Thanks for the insights. I'll just keep my fingers crossed that Paul will do what he can to maintain as much family consistency as is possible.

    I inadvertently "cooked" a couple T3.1's, and probably like a few others, was very happy when Paul added the beefier voltage regulator to the T3.2's.
