Can someone confirm reference lites are cut using a heated sapphire please ?

What is the better option,
Sapphire & Reference Lites - or Diamond and PVC ?

For quality and durability of 7" records to be played in a jukebox ?

Thanks

Nigel

for jukeboxes, PVC only, with a large center hole and 1.5mm thick.
souri made his machine for jukeboxes. it works great.
jukeboxes are adjusted to a bit more needle weight than a usual turntable - about 5-7 grams usually.

the DJ lites don't have a second hole. I've had them slip on my presto before, totally sux.... you need the vacuum plater if you really want to use them. I've also have my chip vacuum actually pull the plate up off the platter, too. They can be hard to cut.

there are prestos with vacuum platters?

I've seen 8's with the vacuum platter. I think I could do it to my 6, since it has holes in the platter for it, just need to figure how how to rig it up.

cool didnt know that, can you upload a picture of your lathe?

btw, you can use a piece of metal which you screw onto the axis of your platter to fix the plate to the platter. like a 5cm diameter 0.5cm thick disc with a hole in the middle that fits onto the platter's axis and another hole from the side into which a thread is cut, then you insert a hex screw, you need a long tool to reach the screw

can't do that b/c my overhead cutting arm, clamps down the record.

Any more on my original thread please ? Its gone off topic.

I currently use 2mm PVC in my 8 jukeboxes and works fine, but was considering Reference Lites instead - on the basis that sapphire cutter styli are far less expensive than the diamond.

I have never had record wear issues on any kind of record in any of my jukeboxes, which I have owned for 20 odd years.
Ok they track slightly heavier, but if set up correctly they are perfect. Its where people dont measure the tracking and have binding trip switches and stiff tone arm cable that starts to bring wear into the equation.

Too light tracking is as bad as too heavy also.

I have played lacquers in them many times and they don't really seem to wear much more after the initial treble drop off.

So far then it looks like the consensu is to continue with PVC.
Souri no good as a source as he only sells to his customers.

Thanks, Nige

Hello Nigie, if you want buy PVC blanks, you can contact Andybee of Mastercut.eu, because he sell the same discs of Souri.
About PVC or acetate, I prefer the first, because it has a low wear of the groove than acetate.

reference lites are a harder acetate coating and sound harsh compared to a dub. I've also heard the PVC has a harsher sound. With that in mind, I'd go with the PVC.

PVC blanks are cheap, and you go through more blanks then styli.

I had a whole batch of 12 inch lites from Apollo that were slightly "kinked" for want of a better word. There was a point on each plate where the surface was slightly uneven. Seems like the thin plates are harder make totally flat? I certainly won't buy again, but if I had to I would ask if its possible to return them if they look dodgy.

Dear Dub Studio. Very Happy

Apollo Masters haven`t no problem to change the laquers happened to me they only ask the serial number that is stamped close the hole and that`s all feel free to ask them.

Take care.
Hamilton. Shocked

The holes in lacquer discs are not drilled - they are punched. If you drill a second hole you will more than likely kink the flat surface of the disc.
