Not sure where I heard it from, I think it might be a hear say thing from someone else.
Haha, typical google not turning up anything to corroborate what I've said. Well nearest thing I've found is that the metal and rubber used on the Technics turntables is military grade, which I think would be a bit overkill for consumer use :)
Obviously turntables were used for military radio and I suspect there would be a requirement for kit to be as durable as possible since equipement gets shifted around all the time during operations, although it's probably all ipod now :(
Also, I maybe wrong what I said about quartz being in circuit for rpm regulation since "quartz synthesizer" is mentioned in the deck name, it might be used to regulate the charging the capacitor, but then quartz is low voltage afaik, really very very little information on what a quartz synthesizer actually is.
