One of the Library's missions is to preserve audio-visual materials. Library employees who work at the National Audio-Visual Conservation Center (NAVCC) in Culpeper, Virginia carry out that mission on a daily basis. One of the formats they work with is old 78 RPM records like this one. Standardization practices weren't what they are today in the early part of the 20th century, so each disc is an adventure. The grooves can be different sizes, and some discs have spindle holes that were punched off-center, meaning adjustments have to be made so it can play properly. This is a quick look at the process of digitizing the audio so that it can be preserved and made more accessible to Library patrons like you! It features Library audio preservation specialist Bryan Hoffa.

I tried to find a forum friendly version to share - but it is just a short watch..

This could go here, or on a drinks thread. This is a picture of the ultimate in home entertainment in the 50's. On the right there is a radio, and above it a record player, and the white speaker grill below. Mono of course. On the left, there is a cocktail cabinet with record storage below.

Nothing like getting quietly hammered while listening to music. It is not mine BTW.

Wow, that's only an hour away, I wonder if they're hiring...I could probably contribute some records from my parents' collection that I inherited.

EDIT:  OHMIGOSH, they are.

"Linn’s innovative Bedrok™ sidewall technology. This technology uses special beech plies that are compressed under high pressure, creating a solid and dense material that reduces unwanted vibrations."

AKA Panzerholz from Delginit 

"Beech-based Delignit® materials feature special technical and mechanical properties (e.g. friction wear and resistance, dimensional stability, breaking load). Beech is one of the toughest and hardest types of wood. It is just 1/10 the weight of constructional steel but has 1/3 of its rigidity. Wood products also represent long-term storage for environmentally damaging CO2 (one cubic metre of wood absorbs almost one tonne of carbon dioxide)."

"Panzerholz®
A DIN 7707-compliant hardened panel material made of a combination of phenolic resin and hardwood with a hardened structure."

https://www.delignit.de/en/brands.html . These guys also do bulletproof versions. In Panzerholz they apply high pressure to the ply makeup before the epoxy goes off, so it ends up much thinner and higher density that just regular plywood. It machines beautifully, can be epoxy bonded (white wood glue does not work), and can be polished to a fine finish. You have to hide the ply edges, (by a 45 degree mitre) or use them as a design feature.

It is astonishingly well damped as a material, and stiff, which is why it has been used in audio products, including loudspeakers.

I has actually been machined to make entire plinths, by epoxy bonding thinner plies and NC machining, or for my slate plinth as a simple 25mm thick support plate.

There is alas little mystery regarding the  "innovative Bedrok™ sidewall technology"

Probably. 

I loved it because it also recorded cassettes. That Walkman, a portable CD player and active Bose Roommate speakers were my system for the fishing boat. I could record other people's CDs.

For 1990 - 1991 it was a pretty great semi portable setup.

If memory serves, that Walkman was about $300 in 1990 money.

The portable CD player was pretty cool too. It had a docking station for AC power supply and a remote control sensor.

The powered Roommates had nice mounting brackets.

A pretty nice rig for the fishing boat. My room was one of the more popular party places.

Remember when I posted in Jacob's Mindless Mindlessing a few months back about picking up a Marantz PM7001 integrated amp for $40 (about a buck a pound) at the local second hand shop?  It's been sitting on top of my dresser ever since, largely ignored.  Yesterday I dug up one of the pair of Technics SL-1200 M3Ds I bought in late 2000 when I had notions of being a DJ.  I've been going through the several thousand records I've accrued in the last 35 years this week.  It turns out that it's handy to be able to listen to a few of them to figure out WTF they actually are.

The M3D is almost too big to sit on the Marantz.  Barely visible on either side are a pair of Rat Shack Minimus 7Ws I got from the same second hand shop.  It's not exactly a high fidelity setup, but works.  Sitting on the platter is the picture disc re-issue of AFX's Analord 10.

Any suggestions on an inexpensive record player for my daughter? She needs something to play her growing collection of Taylor Swift vinyl on.
