Looking for Headshell Socket for DIY Tonearm
 
My friend, Osawa-san makes tonearms and cartridges.

I am trying to find "Headshell Socket", connector that hold headshell. Today, he disassemble used/old/junk tonearm and reuse headshell socket.

Does anyone know where to buy them? I do not want to pay plus $100 for SME replacement.

Thank you!
Kenji

I can't help you, I pull them from old tonearms too, but I have a question for you or for Osawa san: Can you get hold of good quality Japanese pivot bearings?

Hello Mark,

He does not use bearing. Please see this picture.

I looked on E-Bay and found a few amongst the mega-expensive ones for a couple of bucks.

Other than that try a broken turntable at a thrift shop.

Fulken,

That's an attractive arm Osawa san has built. What is the threaded part above the pivot?

dtut,

The thread has Nd magnet. by turning the thread, we can controll tracking force on fly. It is very handy adjustment method.

Mark Kelly,

I talked to Osawa-san regarding bearing. He was looking into them for long time, but cannot get away from 5 points contacts in the bearing (5 balls).

He also tried floating type (magnet, air, etc). If there is no contact, initial attack on sound is slower.

Best,
Kenji

One place to try
 
Only since you asked -- I'm not trying to advertise here. I buy my exotic and unusual audio components from KAB ELECTRO ACOUSTICS and I see that they sell about three vendors' tonearms, but no headshell sockets. Nevertheless, these meet your price target and you can jerk one out of the tonearm. Otherwise, just visit yard sales and thrift shops for old turntables.

Thanks for that. The multicontact pivot bearing is exactly what I want, I strongly dislike unipivots. I am after 6mm OD and 9mm OD; NSK Micro in Japan makes them (BCF9 and BCF6 respectively) but they won't reply to my emails.

I agree with Osawa-san about non-contact bearing problems, IMO these are caused by standing waves.
