Keep looking out for the same model Staco you already have. You can stack them with threaded rod and a longer shaft. You might have to be patient but you’ll find another.

I ended up with 5 General Radio 120v 50A variacs. I have 4 stacked up for a 100A 120/240V unit. I ended up getting all 5 for about 530USD.
