 Dear members

Who can indicate where I to acquire a cartridge for a turntable of the mark Dual Model 300, whose cartridge has a recorded reference CDS310?

Thank you very much,

 José Darte

Robert Sarbell

Hello Jose,

According to the ASTATIC Catalog N-70, their  Needle Replacement for your DUAL CDS-310 cartridge (with 2 tips, and makers number DN3) may be replaced with either a dual sapphire tipped cartridge number N281; or they produced the N281sd – with one tip of diamond and one tip of sapphire. 

N281 tips were: 0.7s/3s ……both tips sapphire

N281sd tips were:  0.7d/3s……one tip diamond and one tip sapphire

Presumably tip 1 was used for the 33/45 rpm speed; and tip 2 (the 3 mil sapphire)was used when the turntable was  playing 78 rpm records

I just checked on ebaY and there was 1 stereo cartridge Astatic N281sd on auction for $8.95 and so, I bought it for you. Item number is 310219503120. . . .

I will be happy to send the small parcel to you when it arrives in a few days.



PD: If you prefer


an original DUAL cartridge, then please advise me and I will just place it with my part

Hello Jose,

Do You mean this Cartridge:

On Top: CDS 310 Original in Brown (unsaleable)
In White: CDS 3 - functionable with Dual 300 (for Sale)

Do You need it with or without needle ?

Make me an offer at my email-adress you found in my profile

 Hello Robert

 I would like to thank your e-mail and it was a pleasure to speak with you again.

Another member of the Rmorg have the proper head and the needdle.

Best regards

Hello Jose,

I agree that the best option would be to acquire the new cartridge and the new stylus.

I will be satisfied to add the Astatic N281sd to my small parts listing for the DUAl turntables. I did find in my old parts bin 2 of the DUAL diamond stylus DN43 which was given to me by my father-in-law in 1965.

I had forgotten all about those old parts.

Best regards,


PD: I am still looking for some parts from the dwarf SABA radio UA345 - like the one repaired by Mario Coelho.
