Current Source for 3.5 Mil Radius

Group,

I have used a Stanton 500 cartridge with Expect Stylus (3.75 conical ) in the past.
Are there current sources for a different cartridge and 3.5 mil Conical stylus ? I seem to have many Diamond Disc Records to record.

I'd suggest you post this to Yankee Trader as a Wanted ad.

There are a number of aftermarket styli in various sizes, but I am currently using Nagaoka cartridges on a couple of my turntables and Nagaoka offers a range of 78 styli in sizes from 1.0 to 4.0. I have the 3.0 (their standard 78 stylus) and the 3.5.

Marc, I sent you a PM. I've been working on custom sapphire stylus for the past year and may be able to help.

This site recommends a 3-mil. stylus for Edison Diamond Disc records, but does have 3.5 available -- https://www.esotericsound.com/CartStyli.htm

The Naga site doesn't tell the prices... How much do these carts cost? And the 78 styli?

Orthofan,

The 3.0 Mil radius for Diamond Disc records from the Esoteric web site refers to a letter (the web site has a hot link that allows you to read the letter) from the Edison factory during the 1950's that gives the 3.0 mil value.

The Edison National Park site had sent out a drawing that shows the original shape was conical and 3.5 mils in size.
There doesn't seem to be lots of info regarding the original design and dimensions available from the Edison Factory that I have found. Maybe a member can point to a good source ?

Ok, the cheapest Nagaoka MP-100 sells in Amazon for $120, and needles cost from $55 upwards. Out of my scope.
A Stanton 500 and a Shure SC35C costed me $35 each, and generic conical diamond 2.5mil 78rpm styli can be had for $25 each.

And yet this YouTube vid does a comparison showing how nice a .7 mil Pickering does with the Diamond Disc as opposed to a 2.5 mil. Granted the 2.5 mil is on what looks like a Shure M78S which I am in the middle of replacing right now due to the noise.

I think that's a Pickering V-15. Basically same cartridge as Stanton 500. Same stylus can fit both.

As I posted in some other thread, I usually use an inexpensive conical "DJ" stylus as my default choice for DD's. I like the results I get. DJ styli can also track at ranges of 3-5 grams usually.

I have the Nagaoka MP-110 and one of the Naga 78 rpm styli. The stylus is OK. It doesn't really track much beyond about 3 grams, kind of like the Shure N78S. May have a hard time with a DD if your tonearm doesn't have adjustable height, because Nagaoka's ride kind of low.

I can't help but wonder how these V-Trace cartridges would do with a DD, even though they are designed for cylinders.
