If my past experience is anything to go by, it can be hard enough knowing what's for sale even if you're there
! I've seen pictures that people have posted of bargains they've picked up and which I would certainly have had if only I'd been sharper-eyed !
Since it's been so long since the last full-scale event I suspect there will be all sorts of treasures that people have accumulated.
For what it's worth, I've just finished testing a CV250A 250V Volstat which will be on my stall. It's giving a rock steady 242V true RMS out into a 200W incandescent load with input voltages ranging from 199V all the way to 266V ! But enough of the cheeky advertising ...
Cheers,
