Whatever have you done to it? AFAIK the 11/70 has switching regulators as
standard (my 11/45 certainly does). Not the normal design of SMPSU (in
that there's a big mains-frequency trasnformer on the input), but it's a
switcher none-the-less.

But I don't lioke changing the classic
machine. Not even replacing
PSUs
with switchers. The original PSU is part of the design, and I want to
keep it that way.
While I agree with you here, I have to admit that, if my PDP-11/70
had switching power supplies, I'd probably run it a lot more often.
