Well done Ben!

The Acos GP96-1 was tracked by Hacker at 5g (if that's any help).

Excellent work!

Does anyone know what the difference between the various BSR stylus types such as ST12/14/15/19 actually is?

Also the list is a bit light on Ronnette, see further attached data from a Finnish website.

The TX88 showed what could be achieved in frequency response and fidelity from a crystal cartridge. Even 'Gramophone' magazine were impressed!

Regards,

Paul

I was going to add an explanatory bit on the different BSR styli but forgot! There is a chart in the document indicating the characteristics of sonotone 2509/3509 styli types, so a similar BSR chart would probably be a good addition. Will get to it.
To answer your question: ST12 is LP/78, both sapphire. ST14 LP/78, but LP tip is diamond. ST15 dual diamond LP tips. ST19 is single diamond tip (not flipover).

Thank you for the Ronette info. Will add it to the next update.

Excellent information Ben.

The TC8S had a recommended tracking weight of 5 to 9 gms, usually set to 7 gms in the BSR changers.

Just a quick update to say I'm working on a second edition of that chart incorporating data contributions made since the first was uploaded.

I'm still after the following data:
BSR
-SX5M, SX5H: output, tracking force.
-SC7M: output, tracking force.

SONOTONE
-8T: tracking force
-9TA (original): tracking force.

RONETTE:
-TO284 : Stylus reference.

I also have a new section for PHILIPS heads and am after data for the following modules:
GP214, GP215.

Hi Ben,

I think the Ronette 284 came in 2 versions, the screw held Pfanstiehl ref. 700 (Collaro Studio type) and later ones had the clip-in version, Pfansteihl ref. 702 (Ronette 105 type). I have a later one but it's packed somewhere safe so I can't check for you, sorry.

Looking at a Vernitron leaflet that came with a 9TAHC I bought recently it says the following:

2T: 9 grams
8TA4: 5 grams
9TA: 2-4 grams. All to be loaded with 1-2 megohm


HTH

Regards
