Ok trivia fans. Why do 45 rpm records have bigger center holes than 33's
and 78's ?

They do not have to make the hole larger to put it on juke-boxes? I too would like to know the answer as 45's in Great Britain (at least) have the small hole as on LP's. The only large holes in singles that I had seen (until I came over to the States) were in old juke-box singles. -- [ You called all the way from America - Joan Armatrading ] [ You're never alone with a rubber duck - Hitchhikers Guide To The Galaxy ] ------------------------------------------------------------------------------ || From the keys of Richard Jeffreys ( British Citizen Overseas ) || || @ AT&T Bell Laboratories, Naperville, Illinois || ------------------------------------------------------------------------------ || General disclamer about anything and everything that I may have typed. || ------------------------------------------------------------------------------

It's my understanding that RCA (I think) tried to establish an "new standard" by putting larger holes into records that went at a different speed. Eventually, the new standard became the standard for singles only, and the competitive standard (small holes at 33rpm) became the LP standard. Why were 78s abandoned? I'm not sure, but I can guess...you can't fit much onto one...it goes too quickly. ...bob garmise...at&t bell labs, columbus...

<eat this> You just wrote the answer. The holes in 45's are sized to accomodate the crude juke boxes of the '50's, which weren't accurate enough to stab the turntable spindle through a small hole. Ken
