O.K. tell me how exactly did you do your conversion?

I run an RA90 in the cabinet as well, but it's connected to the
upper receptacle on the back of the mains box, outside, not the
one inside. I have fried two fuses of two such VAXen with this
maneuver, I dare say it's reproducable, unless you may have done
tricks inside the mains box. I did all my conversion simply by
changing the power plug, so, I never opened the mains box,
except when we were investigating the guts last year.

I'll ask how long they can hold it. I also asked a parts place if
they have that backplane of a -300, -400, -500, etc. If I can get
it for a modest price, I will have the thing shipped, if not,
I'll have them hold it for you to take on "loan" as long as they
will. If it must go in a week, I'll send out a general cry for help.

cheers,
