Worked with implanters up to 200kv......with 20kv extraction.....

Safety is built into those devices. When you open an outer door......a shorting bar descends and shorts the inner terminal to ground. AND than you install the parallel 'chcken stick'......
All doors are interlocked to when any interior door is opened THAT shuts it off, too, unless intentionally defeated.

so I'm not overly concerned with 'only' 100volts.

BUT? I DO appreciate the concern. I've seen some awful dumb stuff over the years......from a guy working on an RF generator on the floor....and someone DROPPED THEIR Stainless Steel TWEEZERS on the board......reached IN and got them out......and no shock.....
And worse......When you deal with some of this stuff.......Even a 'mere' 480 is deadly. Ask the guy who DROPPED HIS WRENCH across the input of a giant transformer. Sound like a cannon and the wrench vaporized......Stuff like THAT.....

sounds like you'll do well. I've managed to zap myself 1 or 2 times. it happens.

I could recommend a supply I bought a time ago, + & - & ground but it was not for hi-fi. I charge car batteries JIC.

Maybe someone else can check me on this suggestion, you can take 2- 50 volt supplies, attach the + of one to the - of the other and that's your middle ground point. Then you'll have the + 50 and - 50 and the ground. I recall years ago having to do this for a similar purpose

  That's what a diagram in the manual shows as what works......An expensive approach if buying aftermarket supplies....
  
  Don't think for a second I've NOT gotten zapped.
  I got zinged by a Tesla Coil maybe mid-60s or so......A very long spark jumped to ME......
  
  But I'm always careful. I hope. One hand in the pocket, when doing certain things.......
  And If I DO NEED to go 'into' a piece of gear? Unplugged for an hour or so prior THAN check any of the big PS caps for residual charge.
  
  Last small project? I re-corded an ancient KENWOOD KA-7100 integrated amp. Upped it from 18ga to 16ga, new straing relief and isolated the drilling so NO CHIPS fell into the map.....Than I checked with a magnet and already had 'sticky' tape near the hole.....I got it ALL.....
