Steel Balls
Kevin, Most model Electroluxes up to the 1974 Golden Jubilee will pick up only 3 steel balls, in 1975 when the Super J arrived and every model after that will pick up 4 steel balls. However, some people do change the motors in the older machines to sort of a hybred motor and it will pick up 4 steel balls, I have a model G that I actually put in a Miele motor and the machine passes the 4 steel balls, it pulls 125 on a vacuum guage where the original G motor only pulled about 85 on the guage. I made a "Super XXX" a few years ago for the 2008 convention, and it had a Miele motor in and it picked up 125 inches on the vacuum guage, I actually coupled it up with a Simplicity Power Nozzle and won the Monster Vac contest, the machine was a beast, I sold it on eBay and the buyer is using it as his daily driver, hat machine was unbeatable.
