this is what is killing me. If you google that product number, it comes as 750VA or .75KVA everywhere.
But here's an interesting page. note the Boost Voltage and the Catalog Description and then way down below, the Power Rating is .75KVA and then the VA rating is 750.
This is why I think the Graig's List GE above is usable.
ACME T181052 Acme, Buck Boost Transformer, 12/24V 750va - Crescent Electric Supply Company
Man I feel like I'm beating a dead horse here, SORRY.
