SME3009 advice - UK Vintage Radio Repair and Restoration Discussion Forum

A friend has dropped a lid on the arm. It has broken what I believe to be called a stabiliser bar. How is it fixed in, is it a new piece, if so what do I search for.

Many thanks.

That's the bias lever that has snapped off - it's what the loop of the bias weight hooks over to provide anti-skating.

I'm not sure if the remains can be removed or if you can obtain replacements. Your friend might have to purchase a whole new upper bearing housing from someone who can provide parts.

I have just found one on the auction site, it says SME 3009 S2 Improved Pillar & Yoke, I only need the yoke, so I have messaged the seller. I looks the same, but the one here says SME 3009, the one above is S2 Improved, it looks the same, not sure of differences.

The rod on the S2 is longer than that on the Improved, as the latter was designed for a maximum playing weight of 1.5g, so needed less bias than its predecessor, which was calbrated up to 5g.

Ted, the arm here is a SME 3009, so I assume one of the earliest? If the one I am looking at is longer, it would be OK, tracking at 2g. I met a guy not long ago who knew all the models and differnces, I am still learning. At the moment the broken bits are a a engineers who maybe able to help, but need all my options open.

The broken bias rod is from a Series 2 as produced from around 1962 to 1973, virtually unchanged. The Improved had the shorter bias rod and a counterweight on a threaded mounting, and some had a fixed headshell. Yours is a Series 2 on this evidence.

Thanks. Makes sense now.

Give SME a call - they have lots of NOS spares, and might just have what you need. They are exceptionally helpful.
