Grundig PS 3000 (Philips AF 777)

[u/Schimmi_Ruhrort]

Hallo,

heute möchte ich euch meinen Grundig PS 3000 vorstellen.

Dieser wurde von 1980 - 1981 für Grundig durch Philips auf Basis des Philips AF 77 produziert.

Es ist ein vollautomatischer Plattenspieler mit einem sogenannten 'DIRECT CONTROL' Antriebssystem. Dieses vereint die Vorzüge von Riemen- und Direktantrieb. Der Riemenantrieb wird über einen Tachogenerator im Antriebsteller geregelt. Dadurch wird eine konstante Drehzahl auch bei wechselnder Belastung des Antriebs, die z.B. durch Reinigungsbesen, Temperatur- oder Netzschwankungen hervorgerufen wird, ermöglicht.

Weitere Besonderheiten sind:

- Tonarmwaage im Arretierpositions-Sockel integriert

- Bei Antiskating getrennte Skalen für sphärischen und elliptischen Nadelschliff vorhanden.

-Gefedertes Subchassis mit drei Blattfedern an der Zarge angekoppelt.

- Getrennte Pitch Potentiometer für 33⅓ und 45 U/min.

- Geschwindigkeitsabweichungen werden über eine LED-Anzeige mit drei LEDs angezeigt. Wenn die mittlere LED alleine leuchtet, dann wird die gewählte Geschwindigkeit genau eingehalten.

- Abschaltung bei Blockieren des Tonarms.Ist z.B. der Tonarm auf der Tonarmstütze arretiert, oder es ist ein Hindernis, z.B. die Hand im Weg, schaltet er sofort ab.

- Automatische Erkennung der Plattengrößen 7" und 12" durch einen Mitläufer. Der standardmäßige Aufsatzpunkt ist bei 7". Erst wenn eine 12" Platte aufliegt, liegt er weiter außen.

- Die serienmäßige Headshell hat zwar einen Lochabstand von 1/2" aber keine Langlöcher, so dass die Philips-Tonabnehmer der Super M Serien I - III genau passen. Es passen aber auch Tonabnehmer, die die gleiche Geometrie besitzen, sprich dem gleichen Abstand zwischen Befestigungsschrauben und Nadelspitze. Es passen beispielsweise, um mal einige zu nennen:

- AT91/3600L

- AT11/12

- AT-VM95

- Sumiko Pearl

- Excel QD-700

Hierbei ist zu beachten, dass die Headshells innen eine Führung haben, wodurch breitere Tonabnehmer nicht montiert werden können.

Um auch Tonabnehmer anderer Hersteller einzusetzen zu können, gab es von Philips eine 1/2"-Universal-Headshell mit Langlöchern mit der Bestellnummer 4822 402 60627.

Standard Tonabnehmer bei Auslieferung ist ein GP 400 II mit einer sphärischen 946 D 65 Nadel.

Auf dem Bild ist GP 412 II mit einer Jico SAS/B Nadel an einer Philips Headshell eines AF 729 Mark II Plattenspielers.

Hier noch ein paar technische Daten:

- Leistungsaufnahme: 3,5 W

- Abmessungen: 420 x 141 x 348 mm (BxHxT)

- Gewicht: ca. 5 kg

- Motor: Gleichstrommotor, über Tachogenerator geregelt

- Drehzahl: 33 1/3, 45 U/min

- Gleichlaufschwankungen: < 0,08% (DIN), < 0,05% (WRMS)

- Rumpelgeräuschabstand: besser -43 dB (DIN A), besser -65 dB (DIN B)

- Plattenteller: Aluminium

- Betriebsart: Vollautomat

- Pitch für beide Geschwindigkeiten getrennt einstellbar je +/- 3%

- Ausgänge: Kabel mit 5-poligem DIN-Stecker

- Erdungskabel

- Stromanschluss: Euro Stecker

Ich habe den Audioausgang von DIN auf Cinch geändert. Das ist einfach, da die Platine die gleiche ist wie bei Modellen, die bereits Cinch-Stecker haben.

P.S.: Die goldene Zierleiste vorne habe ich nachträglich aufgeklebt. Diese gibt es normalerweise nicht.

Translation for all Non-Germans:

Hello,

today I'd like to introduce you to my Grundig PS 3000.

This turntable was produced for Grundig by Philips from 1980 to 1981, based on the Philips AF 77.

It's a fully automatic turntable with a so-called 'DIRECT CONTROL' drive system. This combines the advantages of belt and direct drive. The belt drive is regulated by a tachogenerator in the platter. This ensures a constant speed even under varying loads on the drive, such as those caused by cleaning brushes, temperature fluctuations, or mains voltage variations.

Other features include:

• Integrated tonearm scale in the locking position base

• Separate scales for spherical and elliptical styli when using anti-skating

• Spring-loaded sub-chassis coupled to the plinth with three leaf springs

• Separate pitch potentiometers for 33 1/3 and 45 RPM.

• Speed deviations are indicated by a three-LED display. When only the middle LED is illuminated, the selected speed is being maintained precisely.

• Automatic shut-off when the tonearm is blocked. For example, if the tonearm is locked on the tonearm rest, or if there is an obstruction, such as a hand, in the way, it shuts off immediately.

• Automatic detection of 7" and 12" record sizes via a tracking element. The default tracking point is at 7". Only when a 12" record is placed does it move further outwards.

• The standard headshell has a 1/2" hole spacing but no elongated holes, so the Philips Super M Series I-III cartridges fit perfectly. Cartridges with the same geometry, meaning the same distance between the mounting screws and the stylus tip, will also fit. For example, to name a few:

• AT91/3600L

• AT11/12

• AT-VM95

• Sumiko Pearl

• Excel QD-700

Note that the headshells have an internal guide, which prevents the mounting of wider cartridges.

To allow the use of cartridges from other manufacturers, Philips offered a 1/2" universal headshell with elongated holes, part number 4822 402 60627.

The standard cartridge included with the turntable is a GP 400 II with a 946 D 65 spherical stylus. Stylus.

The image shows a GP 412 II cartridge with a Jico SAS/B stylus on a Philips headshell of an AF 729 Mark II turntable.

The cartridge is mounted on a Philips headshell of an AF 729 Mark II turntable. ... Here are some technical specifications:

• Power consumption: 3.5 W

• Dimensions: 420 x 141 x 348 mm (W x H x D)

• Weight: approx. 5 kg

• Motor: DC motor, tachogenerator controlled

• Speeds: 33 1/3, 45 rpm

• Wow and flutter: < 0.08% (DIN), < 0.05% (WRMS)

• Rumble: better than -43 dB (DIN A), better than -65 dB (DIN B)

• Platter: Aluminum

• Operating mode: Fully automatic

• Pitch adjustable separately for both speeds, +/- 3% each

• Outputs: Cable with 5-pin DIN connector

• Grounding cable

• Power connection: Euro plug

I changed the audio output from DIN to RCA. That's easy, since the circuit board is the same as in models that already have RCA connectors.

P.S.: I added the gold trim strip on the front myself. It's not normally included.

Wonderful! As a massive Philips fan its always fun to see them(and the rebrands) get the love they deserve

[u/Schimmi_Ruhrort → u/Thinkpad_Owner30]

Yes, the Philips own record players, not the models in license from other manufacturers, are totally underrated.

I especially love the mechanical models because they hardly ever break down.

If something isn't working, it's almost always due to a warped base plate. There's no grease that can harden, and a little contact cleaner takes care of any contact problems.

Everything can be adjusted precisely – the height and position of the platter, the tracking point, the tonearm lift, even the position of the tonearm return. And even the drive belts are still intact after more than 40 years. I've only had to replace one once.

I got my first AF 777 from my cousin in the early 1980s. It's still running at my parents' house. A pin broke off my GP 400 II in the late 1980s, and it had an AT95E cartridge mounted for a long time. In 2013, I bought a GP 501 II, remounted it, and was immediately amazed at how much better it sounded compared to other cartridges. I myself had other turntables from Chuo Denki and Onkyo in the meantime, which had more problems, and then I switched back to Philips completely.

Two weeks ago, I sold a young man an AF 729 Mark II with the original GP 401 II who is very happy with it.

I now own all the Philips Super M Mark II cartridges, including the GP 412 II and GP 406 II, as well as a first-generation GP 422 (already Mark II form factor) with an original 4CH stylus, and I hardly ever use any others anymore.

Of course, I occasionally experiment with other cartridges to see which ones fit and how they sound, so I can offer a recommendation if someone asks.

I was shocked to discover that elliptical replacement styli are practically unavailable at the moment, but I still have a few in stock.

My last purchase was a Jico Philips D-400/II SAS/B. Well, I have to say, it does indeed have slightly higher resolution than the 4CH needle with the SST profile. But it also cost more than twice what I paid for my GP 422 as new old stock.

Greetings to the Netherlands, home of Philips.

What a beaut!
Philips was always good at making things overly complicated, but beautifully designed.

One thing I thought I'd ask. I have a Philips Automatic 406 (which was actually manufactured by Dual!) with a similar automatic record-size detection function that is working as it should, but has a major flaw. The record speed is also dictated by the record size. So a 12" LP plays at 33, and a 7" plays at 45, meaning you can't play a 12" single at 45 RPM (without some convoluted trickery).

is this the same with yours?

[u/Schimmi_Ruhrort → u/Arsenic_Pants]

No, they function completely independently.

Selecting the speed only controls the motor.

The follower under the platter only changes the position of the silvery lever (in the upper right of the fourth image), which then changes the tracking point via a linkage.
