Need cartridge advice for Philips turntable

The 312 has a low mass arm which requires a high compliance cartridge.

I had 2 of them in the late 70's for a few weeks (long story) and one came with a Philips branded cartridge and the other with an Audio Technica (sp)? cartridge.

The Philips (whatever it was) sounded sounded pretty good and the AT not so much (kind of bright/thin).

Anyway, I replaced I replaced the AT with a Sure V15 MkIII and was surprised/pleased with how good the combo sounded compared to my various Thorens/SME/Sure V15 MkIII decks.


I also briefly had the 212 version in 1974-75, or so, but is was so affected by footfalls (100+ year old house) I returned it for a store credit.

So...

High compliance, which would rule out the Grado I currently use.

Just Googled the old Philips cartridge I mentioned above and they and their replacement styli are readily available on the used/NOS market.

You would want to go with a 401 (or higher) and not the 400/conical version.

There is also a new Philips 501-II listed @ Thakker for $120/US, but I didn't see any spec's listed.

My decks came with a plastic cartridge alignment guide (fitted over the head shell) that actually worked.

The Grado Prestige Blue is a high compliance cartridge at 20 um/mN and will do just fine in that arm.

You could find Philips MM cartridges
