For the belts, you have three possible choices. One is to go to the oldest TV repair shop in town and ask them to size the belts and order for you. Second is to get a PRB belt measuring device (not terribly expensive, but your local TV repair shop will already have one), then find a way to order from PRB belts online. http://www.russellind.com/prbline/prblinecom_.htm. Third is to contact Gary Stork at http://thevoiceofmusic.com/ and see if you can mail them to him to size and advise/sell you replacement belts. The diameter is measured in thousands of an inch and the length is done by measuring the length (both sides pinched together) and doubling. Maybe others have resources I don't know about.

In the VE library is the AG 400 manual https://www.vinylengine.com/library/phi ... 4000.shtml.
Looking at the parts list and using Google Translate, I see the following;

antriebsriemen gross = large belt - part number TD 650 18
antriebsriemen klein = small belt - part number TD 650 20

Using the google search "philips AG4000 belts", I found a few possibly helpful sites.

https://www.ebay.co.uk/itm/Set-of-2-bel ... 2822915972

The two above seem to be your best option. I feel more comfortable with the ePay option myself.

Hope this helps.

I'll probably order from Turntable Needles as I've ordered from them before. So, thank you!

I'm still a little concerned about the motor though. When I went to work on it again yesterday there were sparks coming from the top spinning centrifuge thing where one of it's arms meets an adjustment screw. And the static noise is still there. The motor does still work so that's good, but I wish I could figure this issue out before proceeding with the speed issue. Maybe I'll try taking a video so folks can see and hear what's going on. Thanks again!

For a new rubber mat you might try one from a larger turntable and trim it down to fit. Or at least a felt.

Those belts are flopping around in the video. It’s obviously the problem. I hope you can find replacements.

I have gotten belts from Turntable Needles/Belts, also, and they are great.

That's actually a governor on top and the contacts need to be clean or they will spark. Use a solvent first and very fine abrasive if that doesn't fix it.

Much appreciated! Will do.

Quick update: I have new belts on the way and I sent photos to my favorite local vintage electronics repair shop (he said he's never seen one of these turntables) and he said he might be able to hook me up with new capacitors. He said he's never heard of a motor sparking, so thinks maybe something is up with it. Thanks again, everyone!

I saw a video on YouTube of a guy who replaced the ones on his and saw how tight the new ones were, so, yup I ordered from Turntable Needles. Appreciated the tip on a new mat.

Great advice! That did it! Made positive progress tonight. I managed to loosen the small screw on the governor to make room to rub both contacts that were sparking with sandpaper, then spray with a little contact cleaner and dry with cotton swap. Then, re-tighten the screw back and now there are no sparks or static in the speaker! I could see the carbon build up using a magnifier loop. Gone now. And the battery power which seemingly had been almost drained came back. I put the phone with RPM app on it and it's running 30-31 RPMs. That's good! The best so far actually. For the mat I'm trying a rubber jar opener for now. Immediately can see its not a perfect circle, but will have to do for now. New belts should be here tomorrow. Thank you!

Thrilled to report everything is working! Adding new belts and cleaning the idler surface did the trick. Here are some pics with the RPM app. Not perfect, but for a 55 year old, battery operated turntable I'm very happy! Thanks again for all the help all!

New belts:

Figured out the tracking weight is about 8 grams. (I used a 5 gram weight to tare from there and then add 3.05g)

For now using the platter mat from my Crosley, which I hardly ever use and oddly enough stopped working yesterday. Kismet.

Here's a short video playing a couple records. I'm planning on making another video showing all the steps it took to get to here. Thanks again, guys!

Congrats! I am happy you got it going. Even at 8 grams it will be much nicer than your Crosley. Records of that vintage had plastic designed to take that weight. I only suggest that you do not play modern discs on it as the vinyl is softer and the grooves are not cut to compensate for the older cartridges. Happy Listening.

Thanks for the advice. Yeah, older records is what I had in mind. It's really why I got a Crosley (found it for $10 at a thrift store) to play such albums I would not risk playing on our main turntables. I can tell the difference already between the few old and new ones I've tried with the Mercury.
