Philips AF 829

Post by denjwass » 18 Jan 2013 02:20

Hello
Just aquired a Pilips AF 829 from a friend who took great care of it since he bought it new.

I figured I could set up and go. Everything seems to work fince except for the fact that the tone arm will not travel over to the platter. Using the automatic function it lowers the arm well short of the table. Likewise when I GENTLY move the arm manually it comes to a definitive "stop".

What's up?? Is it possible that there is a set screw in place for shipping - I seem to remember tables having that. I have no owners manual.

Any help would be greatly appreciated.

Dennis

There is a service manual here: https://www.vinylengine.com/library/phi ... -829.shtml

Thanks,
Looked at it and did not see anything obvious.
Hoping to find a "Users Manual" that might be helpful.

These tables work with LEDs in the automatics. I have an AF-829 MkII that wouldn't engage the auto return function. Replacing the LED solved the problem. Same for the auto-start. I had a 977 that started the automatics, but when the needle hit the record the turntable would stop spinning. LED problem.

Replace all the LEDs inside the table, that will probably solve the problem!

Another thing to look out for: the bottom plate is made of plastic, with a thin metal sheet glued to it (some Philips earthing thing). Over time, this glue would react with the plastic bottom, causing it to deform. This causes a problem with the antiskating; the deformed plastic presses against the mechanism. Check if antiskate works by balancing the tonearm so it floats horizontically, then fiddle with the antiskating and check if the arm responds. I had to cut out a piece of the plastic bottom in order to get the antiskating mechanism to move freely.

I hope this doesn't put you off! I am not a technician in any way, but I managed to fix these problems, and so can you!

cheers,
Japi

Japi,

Can I just replace these LED's with any regular red LED that fits? Got the exact same problem.

I just got this Philips Turntable (it is my first turntable ever) and learning quickly now that it takes some figuring out sometimes ;-)

Here's a picture of the one I replaced:

I got the replacement at the local electronics store (took the old/original one with me).

Ah i'll do the same then! Are there any other things I should think about since i'm working on it anyway? Replaced the belt aswel.

And do I have to like calibrate the arm? Or are the 2 led enough?

Bedankt!

Alsjeblieft! :D

If the arm still has the original cartridge, it should be fine. But it won't hurt to take a good look at the user manual and/or service manual, to fully understand how the turntable works.

And yes, the test I described above --to check if the antiskating mechanism is not obstructed in any way-- can be performed without the turntable being fully operational. So I suggest you do that. Philips turntables with those plastic bottoms can suffer from the deformation problem, but yours might be still OK, maybe it depends on how they were stored.

Wel I've cleaned the leds and that solved the first problem, got a new one now. I don't really know how to describe it so I made a YouTube video of it. It starts at the end and stays there, if I move the arm it skips back to the end of the record.. Got the stylus force at 2 grams, and tried all the weights..Anyone got a clue how to solve it? All really got a new belt and needle.. Thanks!!

The video shows the arm swinging to the 7" position. But what is the problem exactly?

Hi there,
I have that exact spinning problem :
The platter will stop spinning as soon as the tone arm will have come down to it. The thing is, all the leds seems to work normally (they produce light), can they be the problem anyway?
Where to find replacement leds?
Thank you very much
Cyril

Hi, the LEDs are inside the turntable. What I did was remove the bottom and put the turntable on 4 piles of CD's (one for each corner), on top of a mirror. Looking in the mirror you can see where the LEDs are, when the turntable is on.

Replace them with ordinary red LED lights. I'm not sure which ones, but I don't think it matters much.

In my case the LEDs were still working, but they did not emit enough light anymore.
