List wisdom poll - but isn't it also common practice to use an isolating
transformer in series with the variac for safety reasons? In which case,
you'll need one of those if you don't have one already (not been
following the thread closeley, so you may have said you own one already)

It looks identical to one we have at Bletchley actually, in which case
the output is a socket on the opposite side of the case to the supply
input cable (the latter being visible in the photo).
I believe our one is rated at 6A, but I haven't tried it yet (and the
only isolating transformer we have at present is only good for 3A anyway
- we use that one with a matching 3A variac for testing stuff)
