The flyer points out Bally’s 50-cycle motor used for export games, while domestic games require 60-cycles. A game had to be equipped with a motor for one or the other, depending on the game’s destination, along with a transformer for the voltage used by the country of destination.

An article in The Billboard, Dec-7-1963 page 42, announced that, starting with Hootenanny, Bally pin games would have as standard equipment their new motor which would operate on either 50 and 60 cycles, with a universal transformer which may be used with either 115 or 220-240 volts current supply. This solution no longer required different motors for domestic and export Bally pinball machines.
