Tonearm/Cartridge pairing.


Hello to everybody.

My turntable’s tonearm has a mass of 15.6 g (cane + head shell). My cartridge weighs 6.9 g. If I calculate the effective mass of the tonearm the way the maker did (arm’s mass with head shell + cart + tracking force) I get a global 24.5 g mass. The arm + shell mass is 15.5 (15.6 actually); the head shell weighs 10.1g.

My cartridge’s static compliance is rated 20mm/N (I ignore whether it’s @10Hz or 100Hz).

Will someone more experienced than I am please tell me if the cart and the tonearm are suited to each other statically? My cart (Goldring E3) did fine on a friend’s turntable (rega P2) but seems a little ill at ease on mine (Technics SL-1510, ca. 1978).

Opinions welcome,

Thanks
M.

Hi,

thanks for the reply. I think my tonearm is operating correctly - tracking force at 2 gr (digital scale) and anti-skate at a little more than 1.5.
A test record would be a good idea, I'll look for one. While I don't intend to jump on the complex merry-go-round of Perfect Vinyl Replay I certainly care a lot for smooth operation as intended by the makers.

Hi,

I moved the cart from a rega P2 ( which had minor, inherent issues with pitch) to a good, s/h SL-1510, that hasn’t.

Some old records, though, that the RB220 tone arm tracked well, sound very bad on the Technics. Being in doubt as to what can be the cause, and feeling smooth articulation in the Technics arm by hand, I am investigating the only objective parameter I am aware of.

Thanks

Thanks,

I’ll try less anti-skate but the cart is set at 2 g as requested.

The website linked to is interesting, thanks. According to it the cart/arm system should work well.

The korfaudio.com/calculator showed that my arm/shell/cart system works well within the safe rage.
Listening to a couple more records was satisfying. It's probably a worn/dirty LP issue.
I stay with a feeling that the RP220 tonearm on the P2 tracks a little better, but since I don't mean to become an obsessed little Michael Fremer, I will keep the Technics as it is.

Thanks to all for the help.

Thanks,

I have an aftermarket head shell which looks well done and rather the same mass of the original one. The wires look decent enough and of sufficient gauge.

I am 69 and had my first 'serious' turntable in 1975. There surely is something I still have to learn, but it's not to become a vinyl nut, spending my days measuring, balancing, testing, weighing, comparing... spending.
 

Thanks for your remark, but your don't really know what I actually know I fear.

Hi,

I don’t know what in my previous posts suggested that I have so little experience of tuning a cartridge. I apologize if I conveyed an impression of partial inability.. My original question was if arm and cartridge looked compatible from a static point of view.

I have used a digital scale, precise to 0.1 g; I have checked the overhang with a tool, and set the anti-skating a little lower as suggested by dover. I thought it was obvious that if I was mentioning compliance and tonearm mass I was a little beyond merely telling Side A from Side B of an LP record..

As for VTA, the SL-1510’s tonearm doesn’t apparently have a regulation for the arm’s height; I can rely on tiny spacers, but the difference from perfect parallel is, by eye, so minimal that I can’t believe it makes an audible difference.

Thanks for all the help,
M.
