This is a fairly early stereo cartridge and it's most likely it will be a crystal type (as distinct from ceramic) medium output type at c.250mV.

Thanks Edward,
Excuse my ignorance but is that 250mV RMS or pk-pk

From what I have read it is customary to use rms.
There has been much very interesting discussions on the subject, worth taking a look.
Cheers

Hi, with reference to the cartridge data list collated by Ben, I was just curious about the mV output?
Iím a newbie, and it has been suggested, and Iím not questioning the suggestion , that a replacement for my (probably faulty) ronette 105 would be a BSR SC11/12 , but I notice thereís a big difference in output, is this material?
Of course, right now, my HMV 2010 is not working properly so a replacement is required anyway and it may be this in the only option, and thatís fair enough, but like I say, curious?
If anyone can educate me?

Yes, there is some variation in mV output between the BSR SC11M, SC12M and SC12H ceramic cartridges. The H version being the highest.
I suggested these because these are the easiest to source here in the UK, have the correct mounting bracket and have LPS/78 styli. It depends what you can find that is still available. There is very little availability of any other type except for the aforementioned Ronette clones or the more expensive Sontone 9TA/HC.
If you don't want to pay much and are never going to play 78s, then go for the already mentioned Red Chinese Ceramic in a mounting bracket for just £12.00 or so.
Let us know how you get on with what you can find....

If your amp is integral to your turntable, as in
All one original unit, the cart output may be
Critical, esp. If the amp is a valve amp.
But if your amp is a digital conversion type,
Accepts an analog signal, and converts it to
Digital, my best guess is that turntable output
Voltage is not critical. Phono in on such amps
Must meet universal standards and that means
A wide range of voltages. The volume adj. Is the
Compensator.

I was surfing around and found a cart vendor
That listed the original cart for several
Bsr models. It wrote the data down, and posted
It to this thread, but it didnt appear, and now
I cant find it. I will search on line for it agai and
Try once more, soon.

The source for the following is mantra audio.
Cart sc11m with stylus st17 is compatable with
The following turntable bsr models.
2000X, 2000AX, 4800BX, 4800X, 6500X, 8500F,
C-123R, C-129R, C141R, C197, CH0571, P231,
P268, RT521, RT529.
I hope this information is helpful to anyone who
Is looking to find replacement carts for a vintage
Bsr changer. These are the models that shipped
With this cart. Does anyone know if there are
Other cart models that match this one?3

Sorry to rain on anyone's parade, but I must point out a few things.
The problem with such information is that it does not tell the whole story. Although those decks above were undoubtedly supplied with the SC11, they were also supplied with others (or none) - The c123, for example, came with the SX6 as well. There were also production changes and OEM considerations.

In any case, when choosing a replacement cart for whatever BSR turntable, the most important factor, after the mounting, is the output, which must match the amp or system the player is used with. One cannot assume that the cartridges on that list, which does not take such factors into account, will be a drop-in replacement.

Ben, thank you for this additional information. I generally
Agree with it. It is a good idea to obtain a copy
Of the amp spec if one can be found. Also, the
Tuner amp year of production has much to do
With what range of inputs the "phono in" jacks
Will accept. Protocalls change over time. I was seeking to add a correlation
To your excelent thread, which is the best source
I have found on cart/stylus matchups, but does
Not yet include bsr model matches. No doubt my little
Contribution needs a great deal of expansion.
Form and fit, as well as function matter, and if as i have,
One aquires a changer in restorable condition, but missin
It's original cart, a source of information on a possible
Replacement or workable substitute is invaluable as you
Know. Any way, a huge attaboy to you for the work you
Are doing for fans of bsr record changers.
