Grace F-9


Wondering how to tell if a F-9 cartridge is a high or low output cartridge? thanks

The F-9 series cartridges were high output moving magnet cartridges.

Most (but I don't think all) of the F9 cartridges used the same body (I think the F9L may have been an exception), and most were spec'd at 3.5mv. I suspect that the ad you referred to is incorrect, as original literature on the F9 series indicates 3.5mv for the F9E.

I agree with Tannat, though, that it doesn't matter. 3.5 mv vs. 5.5 mv is less than a 4db difference.

The reason I would be concerned about the specific model number within the series, though, is because that determines the stylus configuration. For example, while the F9E has an elliptical stylus, the F9P and F9D were conical(!), according to the original literature.

Hi Rich, The Ruby by all accounts is by far the best of the bunch, so maybe you should look for a spare stylus assembly rather than an F9E. I could be wrong.
Hi Lew,

You're right, with the slight qualification that the exact nomenclature for what you are referring to is the "F-9E Ruby."

As you realize, an F-9E can be upgraded to an F-9E Ruby via a stylus replacement. The designation for the Ruby stylus itself is RS-9E.

The diff between 3.5mV and 5.5mV is less than 2 db.
Lew, make that "less than 4 db." As I'm sure you realize, it would be calculated as 20 x log(5.5/3.5) or 20 x log(3.5/5.5).

Which of course is still consistent with the rest of the statements in your post.

Best regards,
