Dear @sleepwalker65 : But, do you bougth it? or only " came close ".
You will not find a new p-mount with that type of stylus. These are the few p-mount cartridges that are available. You should pass on that table if you want a better type of cartridge!!
You may be correct about the B &O P mount system, but I think it is the standard headshell adapter method that is unique for the B&O. without the headshell adapter it is a normal p mount . But please do check to make sure I am correct on this, before you go ahead with any purchase, obviously. SoundSmith is your best source of info and products if you want an LC stylus.
B&O carts are not compatible with the TP4 System (P-Mount). They won’t fit.
TP4 was a good idea which, had it evolved, may have taken over the TT market, even ’high end’, with its ease, convenience, precision. CD ended all evolution. So P-mounts can be a good choice for MM with "OK" styli/cantilevers, but those seeking better should seek elsewhere... or be prepared to spend to find rare old great P-carts and rebuild them, or ’create’ new P-carts. Or replace the tonearm — but if auto-functions are built into the arm, those will be lost and the task more complicated.
If as you say it’s "one of the best", it probably has a great motor/platter/drive-system — a solid beginning for a turntable ’project’, but only a beginning.
Problem with P-mount, whether it be B&O or the standard type, is that the connection between the end of the tonearm and the cartridge body depends entirely and only upon the fit of the signal-carrying pins to the female receptor. I don't see how that can be rigid enough to prevent minute movements of the cartridge body during play, which would be a BAD thing. Perhaps that's why P-mount or the B&O system didn't catch fire, although B&O persisted.
P-Mount also uses a bolt-through to secure the cartridge. The originals had large knurled knobs for tightening: this clamped the armtube's sides against the cartridge. More rigid than the SME-standard bayonet. Zero play.
These small bolts usually get lost. If you buy a vintage TP4 table, it may have a replacement bolt from the hardware store, with a slot you can't reach and no way to tighten. Or it may have no bolt at all, in which case it's just the pin connection. Seeing that, some assume it's 'just how they are.' They aren't.
If you replace that bolt and tighten it, it's a rigid mount. I use an Allen head, easy to reach and torque.
