Do you mean like this?
https://www.ortofon.com/om-5e-p-551-n-1579 Ortofon OM-5? I think you can get a replacement stylus for that Ortofon (original Ortofon) for $30-40 American. Maybe less.
yep thats the one, but the stylus is lower speck no diamond. So as packadge inerior than the denon this needle is like a philips 410 MKII, not 412 like denon is a diamond not a safier like mounted on OM-5 (origionally till 1987 equiped with 412 spec type diamond stylus. o beware origional philips GP 4... freaks. All current aftermarket needles new despite what they advertise for old philips GP4.... are
a) NO diamonds
b) only those for GP406 are conform orig spec thus sapphier not diamond but atleast conform spec wel made in poland. Ergo best new aftermarket stylus available is gp406 marketed replacement needle with sapphier stylus point; also even for your 408, 410,412 or even stereo only on your GP422 "MM".
The one i forgot is philips 4channel cardridge 422 ($700,00 IN USA and fl 600,00 in the netherlands DM500,- IN former BRD for example and 800 or so retail in canadian), which indeed quad or stereo (if mark III 412 2channel diamond was used) had / has even slightly better specs 20 till 23000 hz, instead of "only" 22500 for the GP412 with 412 mark III diamond needle.
Nobody makes a mm with gp422 specs only Denon MC comes close!
For 412 only the best MM denon audiotechnica Sony and marantz still being made with diamond new needles are as good as an orig. philips GP412 mkIII and the denon MC even a little better but lesser base frequency but 23000 high (500 hz higher). Also the denon MC made by ortofon in Demark is the old philips MC.
Philips stopped making there MC course there 422 MM was on specs as good and on all other specs as there MC; it had even a 16 hrz base frequency even with a 412 mk III needle even. 422MM Cheaper to sell easyer to market, more profitable and higher in demand course less amp TT critical and easy to replace mc needle. Partly same reason GP422 (quad) disapeared 412 one third of the 422 price; quad dead, on 2channel 412 was already 100 % hifi din norm plus and CD came out.
Tonar is thinking of release of orig philips style GP422 MC with orig specs and two channel diamond gp412 needle with is also good news for al owners of philips GP400 till 422 cardridge series. For now the tonar future quad 422 stylus remake wont be offfered
comes only with a orig spec GP412 MK III (diamond tip thus). $1200,- US current thus fixed euro / US dollar exchange rate.
