GE volt-pac units on EBay

Hello list

There are some really nice GE Volt-pac variable-transformers on EBay right
now. They are usually used to control industrial motors. If I lived in the
US, I'd buy these for myself. 

30 amps, 0-227V, 8.3kVA, single phase


30 amps, 0-520V, 15.6kVA(?), three phase wye


Hope this is of interest,
