Adapting Ortofon OM-Series for SP Turntables – Small Batch Coming Soon

[Territorial_]

Hi everyone,

I thought I’d share a little update on a project I’ve been working on recently. I’m developing a production-quality adapter for SP-connected turntables, specifically for the Ortofon OM series cartridge. The goal is to create an adapter that matches the exact geometry and tracking force specifications of the OM series, with a tracking force between 1.5g and 2g.

I’ve designed the adapter to require only minimal modifications to the original turntable, making it easy to install while maintaining the authentic feel of the equipment. I’ve been testing it on Beogram 1202 and 3000 turntables, and the design follows the original style, including a transparent needle holder.

I’m not sure if this is the right place for a project like this, but I thought I’d share it here to gauge interest. I’m planning to produce a small batch of 10-20 units to start with. If you’re interested, feel free to reach out via private message

– I’ll be gathering a list of those who would like to be notified or involved.

Edit: I will add images when we get the final production-quality housings out.

Hi, I buy , restore and sell a lot of Beograms roundbelts  so maybe I am interested, my name on the internet is Beovintage.

I’m afraid I don’t really understand this.  Do you plan to make an adapter that allows the use of Ortofon cartridges in B&O turntables?

Yes, you understood correctly. I’m designing an adapter that allows Ortofon’s OM series cartridges to be used with B&O’s SP series turntables, specifically models like the 1202 and 3000, and similar ones with an aluminum tonearm. This only requires minimal modifications to the turntable.
As for the project status, I’ve already tested the first prototypes and confirmed that the mounting and weight adjustments work well. I’m currently refining the final design for the transparent part, ensuring it also provides proper support for the cartridge and the needle assembly.

Here’s couple quick renders of the product.

That is great news.  I have three B&O turntables (Beogram 3000, 8500 and RX2), and I’ve replaced the MMC4s in the first two at quite some cost quite recently.  They sound great, but the ability to get rebuilt MMC cartridges won’t last forever, so it’s good to see someone working on a longer-term solution.  Great work.
