I have removed the power supply for the memory of a KL10, and that
is really a linear supply. The weight, and power consumption of
that is on a totally different scale to anything switching...
Where have you seen any large transformers in an 11/70 by the way?
I'm talking about the big honkers in the front sections of the
H7420s. Admittedly they're nothing compared to what's in the bottom
of my System/36, but I've had to lift those power supplies. Ow!
