Looks Like I am Acquiring an Ortofon MC3000 MK II

Yes, quite a few Ortofon cartridges from that era had very low outputs, and the MC3000 mkII is one of them. Could be tricky to handle. Getting sufficient gain isn't a problem. Getting sufficient gain with a good S/N ratio is the problem.
Here's a quote from a Stereophile review:

"...it also had a preposterously low signal output of 50 microvolts, which gave new meaning to the terms hum and noise. Few MC preamps had enough gain to deliver adequate driving voltage to a system, and none of those that did had low enough noise to be usable with the 2000. If the problem wasn't hum, it was hiss; if hiss was acceptably low, there would be too much hum. At least Ortofon had the sense to be aware of the problem and to do something about it, in the form of their T-2000 step-up transformer, which is the only device I ever found that would allow the cartridge to be operated without a constant background of hum or hiss. Despite all this, I have used the MC-2000 as my reference cartridge for the last two years. Why? Because of all the cartridges I've tried, it is by far the most accurate...
The MC-3000 differs from the 2000 in several respects. First, and probably most important, is that it has twice the output. This raises the ante to 100µV, still too low for most MC headamps to handle, but nonetheless translates into a significant 6dB reduction in hum and hiss when Ortofon's T-3000 stepup transformer is used. (I advise it; transformer distortions sound less irksome than transistor distortions.) The higher output cannot help but be an improvement."

Actually that review is for the MC3000 not the MC3000 MK II. The MK II has slightly higher output voltage. Specs are as follows

Moving Coil
Output Voltage
0.125 mV
Freq Response
20Hz - 40kHz

Tracking Force
2.0 - 2.5 g
Mass
9.5 g
Channel Separation
25 dB

Channel Balance
0.5 dB
Load Impedance
> 20 Ω
Output Impedance
5 Ω

Stylus
Stylus Tip
5 x 100um Nude Ortofon Replicant
Cantilever
Aluminium

Dynamic Compliance
x 10-6cm/Dyne
Static Compliance
Price

Notes
Black Sapphire Body. Six nines copper coils.


So while that is low output voltage, its not horrible. I have successfully used other cartridges that low with my Esoteric E-03 phono stage, so that is how I am going to start this process off.
 
Will you be using an Ortofon SUT?

Thanks!

Maybe one day I will acquire one of the TOTL Ortofon transformers, such as the T3000 or so on, but do not have one at this time. I have used cartridges as low as .09 mV with this phono stage that have sounded excellent and not had noise issues unless I am very very high on the volume setting. My electronics chain is Esoteric E-03 phono stage/Halcro MD-8 pre-amp/AVM Audio AMP Essential Monoblock amplifiers.
 
Actually it does.

"On the other hand, the MC-3000 is unquestionably the second most neutral cartridge I know of. That's damnably faint praise, considering its higher price than the MC-2000, but unless I can persuade you to trade in your SME V or Alphason 100 or ET 2 for a Souther, a WTA, or a Versa Dynamics (footnote 3), so you can buy an MC-2000 and suffer with the hum, you're better off with the MC-3000 than anything else I know of.

You can be assured, though, that the MC-3000, like its forerunner, does not sound like the average MC. It is much more up-front and alive, much smoother at the top than most (more delicate, less flashy), and more expensive—particularly when you count in the transformer, which is a virtual necessity. (Ortofon says a number of users have been able to do without it, but that's something I would urge you try, at home, before buying just the pickup.)"

However, one point to make. This is the review for the Ortofon MC3000. The cartridge I bought was the MC3000 MK II. Not the same cartridge.

This cartridge has been bought for the purpose of being my casual listening cartridge, to keep the hours of my Transfiguration Proteus, ZYX 4D, and Ikeda 9 Kawami. What I need it to be is a nice sounding cartridge for what I spent. How it compares to the MC2000 is not as relevant, as I am not looking to duplicate that level of performance.

From what I am finding out from those who value the classic Ortofon TOTL cartridges is that a properly operating MC2000 with OEM cantilever still in place is very very difficult to locate, and those are not selling for cheap money. You will need to locate a SUT or a custom built pre amp stage to use it. This will be significantly more expensive than what I paid for the MC 3000 II I bought. Now if you want an easier to use Ortofon that performs on par with the MC2000 apparently you want the MC7500. Apparently they are on the same level of performance but do not have as low an output level or such high compliance characteristics.


Seems like the extra output voltage of the MC-3000 II may be better. In terms of S/N of the system, compared to the MC-2000. :idea:

Yes, the mkII does have a higher output - 0.125mV as opposed to 0.1mV. That's just under 2dB higher. Not huge increase, but an increase anyway.
 
0.125mV output works with both my SUT, or SS Head-Amp, with no discernible noise from 10 feet away. I also tried the MC- stage built into a Tandberg Preamp, and I couldn't distinguish "noise floor" from vinyl whoosh. I prefer the SQ of the xformer, but that wasn't the question.
 
So the cartridge arrived yesterday, well actually the day before but no one was home to sign for it, so I had to pick it up at the Post Office on Friday.

Opened the box, and its packed safely but its the cartridge only and stylus guard, no mounting hardware or box. That's OK but I don't think I have any spare aluminum bolts and nuts, so I am going to have to scavenge some.

What I was really interested in was the cantilever. Its a bit of an odd one in that it is grey in color so must be some sort of aluminum alloy, Its a bit largish in diameter and hard to see the taper. But when I compare to other pictures on the net it does look to be a match. So from what I can see it is an OEM cantilever, which was important to me. So a fresh line contact diamond on an OEM cantilever is the best I can hope for from a vintage MC cartridge, and this should be a good cartridge for being a daily driver.

The body is in fine shape with no signs of careless mounting or abuse. It is nice having the original stylus guard also. So I should find time to mount this up this weekend. I might have to swing by a hobby store and look for some nylon bolts and nuts. I have used them for cartridge mounting before. I would probably rob the aluminum nuts and bolts off the MC200 I currently have mounted up and transfer them over to the MC3000.

Looking forward to listening to this cartridge, as I have always enjoyed the upper end Ortofon moving coils.

Maybe it's oxidized aluminum, it can be a sort of dull gray color. I dunno if it makes a difference compared to plain old aluminum, though it's supposed to form a hardened layer. It at least used to be a thing in phono cartridges.
 
So these are two pics I downloaded off the net of a MC3000 MK II.

Now here are the best two pics I could take at the moment, all I have is a cell phone.

Does it look right to you? Comparing the photos I don't see anything that would worry me. Mount that thing up and give it a listen! I'm curious where you think this cart falls compared to Ortofon's current models that you've reviewed or used.

I have it installed and an initial alignment done. The USB scope came in DOA, it seems like Amazon warehouse did not check it out at all. It wouldn't even turn on. Would be nice to have one to do a cartridge alignment though.

I also installed some Furtech silver cartridge leads, so those need a bit of break in too.

But have my first album spinning and so far so good, no significant issues so it's a successful purchase.
