I just got mine in today. FYI, for anyone who is in the US, I neglected to notice that this unit come set to 220V by default. Although I am not very good with transformers, I noted in the manual it said that the taps could be changed, so I decided to open the case and take my chances :-). It has two windings in parallel, with taps for 0, 100, 110, and 117. There was a jumper connecting the two windings at 0/110 (for 220 total). I unsoldered that, and unsoldered the remaining wire on the second winding to 117V and resoldered it to 117 on the first, crossed my fingers to avoid the magic smoke and turned it on. I was greeted with a nice orange glow across all 5 tubes showing zeros! I've never actually used a FC before so I have to figure out plugging something into it to check other digits but it looks to be in working order as far as I can tell.
