Awesome Danbury Mixer at 2:52 - anyone have more info on this type mixer, basic mechanics of how it works, basic diagram?

Wow--now clasical music isn't my favorite--I would've been happy to work the shift that produced all the cool BLUEBIRD 78s by Tampa Red, Washboard Sam, Montana Slim, Monroe Brothers etc...

this was during WWII, A lot of the men were fighting in the war, so companies had to hire women.

CDs have one side because that's all you need for a typical album and it simplifies manufacturing; dual-sided discs can be more complex to craft, such as DVD-18 which is dual-sided with each side being RSDL or Reverse Spiral Dual Layer. Maximum duration for a redbook CD is around 80 minutes while the LP may yield around 20 minutes or more for each side, depending on how the grooves are cut. But, when cutting vinyl, you must balance time with quality; more time will cost you in sound quality.

Not necessarily. The electroplating process is done at the atomic level where copper or nickel atoms are attracted to an oppositely charged object. This is far more miniscule than the actual grooves or, even today, more miniscule than even the pits and lands in a Blu-Ray Disc (the basic principles of creating the pressing molds are essentially the same today). This is why there's no loss in quality. It's only if the data is smaller than the atoms themselves where loss would occur.

I'm sure that the test listeners didn't listen to every single record from every single yield. They likely listened to sample records taken from each yield. Usually, a defective sample record may reveal a problem in the entire yield that the defective record was taken from. A bad sample may prompt closer scrutiny of the yield that it came from and, very possibly, rejection of the entire yield as well as locating and correcting the problem where ever it may be in the manufacturing process.

Man,what a process! Bet all those secret chemicals had their effect! I'm told that before they developed the mother/stamper process, they could anly get a certain number of records out of a master, then the artist had to try and recreate the performance. A while back my wife asked why it took them so long (1906-1908?) to figure out you could have music on both sides of a record. Nobody considered it I guess. Hey, how come CDs only have one side now?!? At least there are some 2 sided DVDs.

Pure Genius. Imagine how fun it must have been to selecta record and put it on the player back in the day...music had allot more respect back in the day.

I have a bunch od 78's and they're all in great condition, I don't think their brittle at all.
