Hey, Gunther! My 6320 has an RA92 in the cabinet that works just fine. I
converted the VAX to run on single phase, overloaded two phases onto one
120V leg inside the box where the power cord goes in. I didn't check what
fuse was installed though. I can give it a look if you want.

I might take you up on that 4200. Can't say for sure because I've somewhat
overextended my wifes patience(sp?) with my hobby. Is there a
gotta-be-gone-by date?
