All of the operations of my record player are fully electronic. I even have a repeat button. Obviously you have to put on the record yourself, but everything else after that could be done with a remote.

Nice to know you use DENON TT!
I too recently revived my DENON DP-57L in my DSP-based multichannel multi-SP-driver multi-amplifier fully active audio project (ref. here).

If you would be interested, please find here the latest setup of my system as of August 3 2023.

For completeness (in misinterpreting/ruining a joke ) -- here's the Accutrak Accutrac I didn't keep. This one was scroungier than the one that's still here.

I believe the arm's belt driven.
The cartridge uses a light (IR) and a photosensor to discriminate between modulated and unmodulated bands on an LP. I don't know how the system feels about translucent or colored disks.
You can read a transcription of the sales brochure blurb at https://stereonomono.blogspot.com/2010/10/adc-accutrac-4000.html and the manuals are available at the usual places (e.g., vinylengine).
Stereo Review's test of the Accutrack EDIT Accutrac may be found starting on pg. 42 of https://worldradiohistory.com/Archi...iFI-Stereo/70s/HiFi-Stereo-Review-1976-09.pdf

I've never even plugged in either of the two that are or were here -- I don't know if the tt can be tricked to work in the absence of the signal from the cartridge (and, needless to say, the styli were/are bad or missing).

Quite familiar with the b&o linears - I do have one of the later, lesser models (a TX-2) -- no track seeking functions on the TX-2, though, of course.

My wife told me that she'd had a mangiadischi in the 70s, and that it was probably still in the basement of her parents' house.

Okay, I admit I had to look that one up.

(Heathkit sold the Accutrac sort of under their own name for a wee bit)...

24 mechanical switches that were (probably) hardwired, to bunches of individual transistors somewhere... and no one had even heard of a uP as a traffic cop!
It really gave me a flashback... as to what we considered fun in those days!

Well... if Heathkit had actually worked its magic on the AccuTrac platform -- it would've had a keypad. Or maybe a card reader slot. Or both.
You know, like their (fairly) early digital tuner.

EDIT:
1) JK about the card reader. HH Scott T33S had that.

Just a web image -- it would be way cool to have one of these, though...

2) Yeah, yeah -- tuners are not turntables... I know, I know...

Sonofix was a kickstarter dealio, which raised about $100K.

That looks suspiciously like a Roulette 45 rpm record on there -- that may have been a clue!

Morris Levy Gets 10-Year Sentence : Roulette Records Chief Fined $200,000 in Extortion Case

Morris Levy--longtime president of New York-based Roulette Records and one of the most colorful and influential figures in the U.S. record industry--was sentenced to 10 years in prison Friday and fined $200,000 for conspiring to extort a customer in the 1984 purchase of more than 4 million…

JIMMIE ROGERS – Jive Time Records

It sounds like the plot of a 1950’s film noir movie. It’s December 1st, 1967. A man leaves a party. As he drives down the San Diego Freeway in the San Fernando Valley he sees a bright light in his rear view mirror. The light gets brighter so he pulls over on a side road.…

I realise my new TT fetish object (and I don't actually have a turntable, or any records) is better placed here. The clean lines of a Rega with enough additional technical eccentricity to make it interesting. I can say it costs more than my car, but I have a pretty cheap car. I haven't checked the whole thread, but some nice things posted here, fun to own.

That's a really sweet air bearing arm!
I'm not much of a fan of that table design, but the arm is a killer.
Sadly not very appropriate for the audiophile choice moving coil needles.

Hi @Sal1950,
Can you explain (a bit) why that would be?
Just out of curiosity and not that I am going rush down to the store to get me one!

In short, the very light arm assembly and near frictionless design of the air bearing is most appropriately mated to high compliance cartridges like the moving magnet designs best shown by Shure and Stanton of the time. This allows them to track well at 1g, thus lowering wear on both the LP and needle. Other factors also become involved.
Low compliance cartridges (moving coils) should be mated to high mass tonearms for best results.
A long and complicated subject on which many opinions rest.
Here's a little deeper explanation on the subject.

That's the DP-47F? My wife has a slightly older/cheaper/less automatic Denon that is dead and doesn't seem repairable. (Downside of all the electronics.) Can it select tracks using the remote? If so, how does it sense the location?

My much-lower-end Technics from the same period is all mechanical, and last summer I got everything working again, even the mechanical auto-repeat. It is in a vacation house, now I am back home and find using my (manual) turntable too tedious by comparison.

Sadly, it doesn't have a remote, nor was there ever one. I was just saying that it would have been possible, there is no good reason not to have it.

No cover?
My MK2 did not have that "reset" button on the 'pitch adj.'... but there was a detente on the slider when at '0' marking.

Cover is removable, it was just off for the picture/when I play records. The mk5 had the reset button on the pitch adjust.

Since no one has posted this one yet, here's my Denon DP-51F that I bought new in 1985. I have bought a Shure V15 Type IV in the previous year and got it installed in a Yamaha TT but moved it to the Denon when I got it. Later on I upgraded the needle to MR version which I still use. I bought a CD player right after that and did not use it much so I'm pretty sure the MR needle has only 100 - 200 hours on it. The TT was stored for almost 20 years until I took it back to use a couple of years ago.

In the pictures there's a prototype RIAA of my own design that I built in 1989. The tonearm is really something that you cannot get any longer, anywhere unless you find a Denon or perhaps a Sony from this era. It has active damping, tracking, anti-skating and stylus force with linear servos. These servos also lift and move the arm gracefully and silently.

Oh, this seems to also be my first post here although I have followed ASR almost three years now.

From https://www.mysonic.space/biotracer-turntables :



Think of it like multi-axis image sensor stabilization for a camera... only it's for your tonearm.

It's one of those things that later 'high-end mass-market' turntables had (Denon had their variant as well) that is just worlds beyond what you can get these days, at pretty much any price.

Here's mine:

Yep, just got one in good condition

 

[Angsty]

I wonder, if these active tonearm turntables were so good, why aren’t the high-end players today making similar versions? The technology is at least 30 years old now and surely many of the patents have expired. I don’t even see Chinese knockoffs.

How well did they measure back in those days?
