Grace F14 MONO cartridges and styli


Dear all, i have to start this thread because i’ve come across first MONO cartride in my system.

The cartridge is extremely rare Grace F14 (MONO) LC-OFC from the mid 80’s.
I’m a huge fan of the Grace stereo cartridges, in stereo world the F14 LC-OFC is superb, this MM generator is the best ever made along with LEVEL II LC-OFC. As you might know the Grace made so many different styli with different cantilevers and different diamonds for F14 and LEVEL II series in the 80’s.

BUT I know nothing about mono cartridges, because i’ve never used any of them.
And i don’t even have enough MONO records, but i got some for sure.

I don’t play 78rpm SP ... and most of my mono records are 45 rpm (7’inchers) from the 60’s, 70’s, maybe a little bit from the 50’s.

My F14 LC-OFC cartridge has ONLY 2 PINS (not 4 pins like stereo versions). The special lead wire designed for use with mono is included, no problem with that.

Looking at the MONO stylus on my F14 MONO cartridge i realized it is not an SP version described here (definitely not a huge 3 mil. tip), but a nude stylus tip, small just like stereo tip on some other Grace styli that i have in collection. So it’s a good news, because i’m not gonna play 78 rpm anyway.

What i realized by trying this cartridge/stylus on my mono records is a lower compliance of the stylus compared to normal Grace (they are high compliance). The stylus replacement designed for F14 (not for older F9), the plastic shape of the F14 is always different compared to F9.

I’ve searched for MONO styli shapes online and i’ve seen many articles about oldschool conical styli of the different size for the mono records from the different eras. Also about the mono cut on stereo cutterhead.

I could find only one more Grace mono cartridge (LEVEL II) with 1 mil. conical tip described here

BUT this post on another forum is the most interesting:

"I play a number of vintage monos (primarily stuff from ’58 to the mid 60’s, admittedly no pre ’57 stuff) here with a modern microridge stylus and would never go back to using a conical on them (having done so in the past). They sound incredibly good with the microridge...

Based on my experience, I feel all the talk of conical styli being necessary to get the best out of mono records is urban legend at best, if not patently false."

If this is true i can use any stylus on my Grace MONO cartridge for my records pressed in the 60s/70s in mono ?

I don’t have a mono switch anywhere on my gear, but since the cartridge pins are designed for MONO only, i believe, i’m safe to cancel vertical noise caused by conventional stylus with vertical compliance ?

I can not detect a stylus shape yet, it can be Conical, Elliptical, Shibata (or maybe even Micro Ridge). I’ve heard they are all good for MONO made with stereo cutter head in the 60’, 70’s or even today.

Let me know what you think, it can be my first mono cartridge then.

Yes.

Looking at the headshell from the front, right side up (not upside down!) you want red to upper right and green to lower right. White upper left and blue lower left.

Looking at the cartridge from the rear, right side up (not upside down), you want red and white to the left pin, blue and green to the pin on the right.

That’s the way the Denon 102 should be wired so I’d try that first anyway.
We’re looking at Denon 102 just as a guide? Because i don’t want another mono cartridge.

My Grace F14 Mono has been pre-mounted on dedicated Grace headahell with leadwires already connected (correctly). I’m checking all my new carts with Test Records first (Hi-Fi Test LP) with various high modulation grooves for suspension check (no skip btw), then with Ultrasonic Stylus Cleaning (Cardas Sweep LP) and finally with the music, but in the headphones.

So my Mono 45 rpm 7’inch records from the 70’s are really good with that Grace Mono, no hum detected in my headphones. Loaded at 47k Ohm. Stylus has vertical compliance just like stereo stylus. Stylus size is small just like stereo stylus tip.

Not sure what am i missing?
I'm not sure what I'm missing either. Just totally confused at this stage. Thought you were asking for guidance in hooking it up and you're already hooked up.

Thanks @hdm , but It was @lewm who said that something wrong, see below

 Chakster, the way you have hooked up your Grace to your stereo system could cause a degradation of performance, because each channel of your stereo phono stage is now seeing the output impedance of the cartridge in parallel with the input impedance of the other channel.  

I was more concerned about MM stylus type and the compliance of the stylus (just like conventional cartridge).  
Chakster, you’re doing nothing wrong. The purist approach would be to hook up only one channel to the cartridge. No need to go that far. A mono switch would make no difference as far as impedance matching at the headshell.
