Indeed! It seems that the "rubber" parts are quite important. I saw one article or video a few years ago where rubber band pieces were used, but that is not a durable material. This all-weather electrical tape looks better. The same rubber as used for phonograph motor mounts would probably be best.

Dont bother,
The output sucks... It cant touch the 3 volts needed to make a good sound..He has it hooked up to a stereo.
Search this forum for piezo and see my posts and videos..
Real crystals are best...

Where do you find real crystals?

You have to steal them from good 3V crystal carts..

There are so many wrongs in this video, I don't know where to start...

Of course, the result is...well...awful, even connected to a stereo sound system at 4...

You really can't tell from the video how well it sounds but it seems like some of you know first hand. The main reason for doing this is that the players using them track at a very heavy weight. I replaced one of these carts in my Zenith 7S682 with the 911 plug in type fitted with a 78 stylus. I don't care for it much for two reasons:
1. Many of these older players either don't have weight adjustments or, when the weight is reduced, the automatic changer doesn't trip at the end of the record properly. I reduced the weight as much as possible but it still seems like too much weight on the stylus. If I recall it is around 12 grams but the cartridge max is 8.
2. This 911 cart is an all inclusive cart and stylus. So when the stylus wears out, you need to replace the whole cartridge. But that might be a good time to see if I can remove the crystal for the original cart!

But for lack of anything else, this sounds like a fun experiment!

There was a descriptive article on rebuilding these which I thought was on the Philco radio web site but I can't seem to find it now. It suggested using a latex glove for the rubber parts.

Yes, Syl (Old Radioz), author of the post above yours, wrote that article.

Ken... you are right. Syl was the master. As i recall, Syl had medical and personal issues, and is no longer active in the hobby. There were some insults relating to Canada, which was even more unfortunate.

As info, RAR+P is still active. It was the predecessor for ARF, back when usenet was in its glory days. One might be able to search the RAR+P archives for posts by Sylvain relating to his crystal cartridge rebuilding.

Great job Syl! It was very well written along with photos. I think I had printed it out a while back but not sure where I put it. The winter is coming fast. Hopefully I'll find time to give this a try. I've got nothing to lose except time!

Am I missing something here, or did Syl himself just post on August 30, 2016?

You can buy ceramic stereo cartridges on eBay for 2$ each, shipping included!

I bought two to rebuild some of my cartridges (I haven't touched a radio and phono in eons,
thanks to a collegue at work, I restored a phono and soon another nice Rogers radio for him).

These ceramic cartridges are just enough to rebuild cartridges for 45 players (about 1.2v)
a some Astatic and similar heavy 1.2V cartridges (I could share a list).
I've seen a seller offering a similar cartridge with an adapter to fit into 45 player for 45$!
With a bit of ingenuity, anyone can do it for about 2-3$...

Heck, at two dollars a pop, yielding two ceramic elementsallowing for two cartridges rebuild, anyone can afford it
even for a learning purpose.

I can share an eBay link to those cartridges or search by yourself. Let me know.

Yes please, I would like to know my options as well, as I have ordered a few piezos after watching the same video. I need to repair/ rebuild an Astatic L26. If there are better choices, especially ones that lighten some of the wear on my 78s, I will listen to any advice.

No Jeff, and no Dave..
I have run at least 10 experiments with piezo's and the sound sucks.
IThe carts on eBay are good for 45 players but not 3v crystals.
Unless you build a preamp.
I have used a few different carts to rebuild with. I dont remember the exact numbers but any 3v crystal cart will do.
No one wants to give up their sources or the cart they use as to not have everyone buy that cart and then they have no more...
I wrote to West-Tec and they ignored my emails. They suck at building carts and then blame you if they don't work right..
Too many horror stories to fight that thinking...
I will look in my scrap pile for the empty carts I used...

Kirk

Thanks Kirk. Glad to know about west-tec as well. That was my backup plan if rebuild was not successful. If you figure out which cartridge I need for the parts, can you also give any tips for the rebuild? I would prefer not to screw anything up :D
