Doing research on boost/buck transformers, I learned that it is not the 120 volt load that determines the KVA needed, but the load on the lower voltage winding that does the boosting or bucking.  This only applies when wired as an auto- transformer, SOLA rates their 120 volt .25KVA unit at 20.8 amps at 120 volts.  You can put your whole vintage station on one and get 1950's 110 VAC for 50 bucks or so for this size unit from several sources.
