1942 LP manufacturing

[Radioeng2 33]

Actually, I'm not sure you'd call them LP's at all, but you get the idea!

 

Have you ever heard the "playing the stacks of wax" thing?  I've heard that a million times and never gave too much thought to it, though I knew it had to do with the process.  These video's show a bunch of really interesting stuff about the manufacturing process they used at this point in time!  Really interesting to a technology geek like me!!

Hey Mark. Nice to find you here.

I missed you at the Fest this year. Only my crappy CD's to mark the occaision.

 

Try to make it next year.

 

What have you been up to?

Hi Frankie!

 

Yup, I sure missed out not being able to make it and hated it something awful!  I sure missed seeing all you guys!  Events just transpired to prevent going.  Sometimes life gets in the way of the fun stuff. 

 

We'd done a long anticipated Alaskan cruise (),  had extra expenses this year and so on.  Down to the last minute, I was still hoping to be able to slip over for a day...or two...but even that wasn't able to happen.  Sounded like it was the usual good times!

 

I've been playing audio plenty.  I'm just about to complete the beauty stage of a full-range driver speaker project, a Western Electric based pre-amp project and gathering parts for another tube amplifier build.  I hosted a Zu Audio show at my house just a couple of weeks ago too.  That was a really good get together and heck of a lot of fun.  Anytime you can get a bunch of audiophools together, we seem to manage to have fun in some kind of nerdy way!! 

 

And I will hope to be able to make it over to CF next year and catch up with you and all the guys!   Those kind of deals are such fun and being able to make friends at those events is really neat!  Thanks for the shout out!!  Be good and watch out for those speeding Prius!!

That is pretty cool, Mark.

So, if I've got this right, the wax would be a positive (like the final record), the master matrix would be a negative (inverted grooves), the mother matrix would be a positive (i.e., playable), the stamper would be a negative (of course, it has to stamp records), and the final record a positive.  5 generations!
