The solution was right under our noses, but it took a week to see it. If I recall properly, we sent 60Hz to the input, slowly cranked the output, and found 115vac on the terminals. 60 seconds later, the output was connected to a normal wall outlet, and during that and subsequent tours, we never had a drop of trouble with line freq synchronization.
FWIW - the Hammond is the only motor driven instrument on stage. Everything else can get away with 56 HZ or 62 Hz.
Side note: I bought my first JBL 4320s in 1971. Then bought a 2nd pair. Still have 'em, still love 'em. And here's the kick: they're guaranteed for LIFE.
The foam surrounds on the 2215 LFs have disintegrated from components in the ozone *FOUR TIMES*. Complete rebild cost absolutley zero. A call to Northridge, I selected a quality recone shop locally, JBL shipped complete rebuild kits out for all 4 2215s, and replacement = no charge. Amazing for speakers originally sold in 1971.
Plenty of interesting recording data at my site:
Best,
