This ad appeared in a 1978 edition of Japanese magazine Stereo Sound. Not reading Japanese I can see it is a model 4824 but made by ?

Image from a current e bay ad for the magazine,sadly not the turntable.

Interesting not a clue. Looks like a Japanese Mapleknoll only with a captured bearing. :) Wonder if Alan Sliski is still here?

It looks as if it would belong in a console. Perhaps a "high end" console upgrade, 1978 style?

The disc on the front right hand of the top plate says "Air Float".

I'm pretty sure that table never saw the inside of any commercially made stereo console.

What are you basing that conclusion upon?

Could it be some sort of early Teragaki?

The disc says Something illegible (but too short to be Teragaki) followed by Air Float and Model 4824

In other words: you made it up.

Seriously dude, look at the table and tell me what console you think that might have possibly been used in. It appears to be a very high-end Japanese table with an air bearing arm with pressure gauges built into it. How many consoles have you ever seen in your life with a table like that? Zero I'm sure. Outside of Lyric Hi-Fi who used to have their own custom cabinet shop back in the day and actually built consoles with very high-end gear built into them, no commercial console that I'm aware of ever had high-end components built into it. Most American consoles had a BSR or Garrard cheap table built in and many that weren't recognizable by their manufacturer. I think the 'best' turntable I ever saw built into a console was a Sylvania unit that had a Dual turntable built in.

I never said it was anything more than a guess, but it's a damn good one. An air bearing tonearm with a pump installed inside of a console? Really? Like I said, common sense.

A shot in the dark.

Look, if you have an ace up your sleeve and you have a picture of that table inside a console, let's see it. I'm basing my guess on common sense and 50 years of experience looking at and listening to audio gear. From what I see from you, you just want to be cute and argue. I'm in no mood for nonsense. Put up or shut up.

Not arguin'. Just exposing your transposition of guess for fact.

Being cute again I see. I never said it was fact, it was and is my best guess just like you want to argue it was mounted in some console. That's your guess. I'm willing to put money on my guess. By the time air bearing arms hit the market, consoles were dead in the marketplace and were and are far too sophisticated for use in a console designed for housewives to operate.

according to my better half who is fluent in nihongo, its a Makara model 4824. beyond that you'll have to do your own research.


PS - theres and abstract with the US patents office in Los Angeles ca 1978 the inventor is Robert Cheeseboro.

Well that hoo-hah will teach me to not be curious about such contentious issues as obscure 1970s Japanese record players.

Thanks Puroagave .Translation much appreciated .Wading through the Cheeseboro patent application it appears that the only reference to the Model 2848 is a reference to a technical paper about the Model 2824. Cheeseboro's patent seems to have nothing to do with the "Air Float"( bar linear tracking) but concern motor driven radial arms and sealed machines with zero tracking force.

Interesting, not referenced here. Rabinow filed his patent for the air bearing arm in 1967. (Great history of the development of the air bearing arm.)

http://www.google.com/patents/US4455641

I wonder if that was ever a real product???? Or a one off?

BTW, Alan Sliski, one of the air bearing arm's co-developers is quite a researcher and inventor (many years ago we met and collaborated on a project) . Don't know how many of you have seen the new TV ad (at least in the NY area) for using protons (once again) to treat cancer. One of the basic issues with using proton beams is spreading the energy peak out over a usable distance so as to totally encompass the tumor. Alan and his co-author developed a means of spreading out the "Bragg peak" and this research has revolutionized the use of proton particle beams.
