Need RCA loading plugs

Have you tried it without loading? I have a JLTi which I run without loading plugs. It runs a Zyx 4D LOMC very nicely at 47K .It also ran a Benz Ebony L without loading. If your preamp is stable enough it may run without the loading. But you won't know til you try it.

Steve, Does your Einstein provide two pairs of phono inputs that are in parallel with each other, electrically?  That's the only case for which the simple solution offered here would work, simply.  Otherwise, you would have to piggy back one RCA plug loaded with the desired resistor into another that receives the signal from your phono cartridge, or use some sort of Y-adapter.  Still doable but maybe not so simple.  In addition, there is the possible signal degradation associated with using so many connectors in the signal path, a bugaboo of those afflicted with audiophilia nervosa.  I would solder the load resistor directly into the circuit, inside the box.  And maybe that does take some chutzpah.

Thanks everyone for you help. I recently purchase a Haniwa cartridge here on audiogon which has .8 Ohms internal impedance.
I have tried it with my 150 Ohm loading plugs and it sound excellent except the highs need a little more dampening. Lewm the two pairs of inputs are wired in parallel on the Einstein. 

Assuming you are referring to the Haniwa HCTR01, I note that the Haniwa phono stage that is recommended for use with it has an input impedance of only 4 ohms (!), undoubtedly as a consequence of the ultra-low resistance and ultra-low inductance of that cartridge. And it is indicated that tracking force can be significantly reduced when that loading is applied. So load resistors having values in that vicinity should presumably be among those you try.

As Ralph of Atma-Sphere has explained in various threads here, and as alluded to above by Artemus_5, the design of the specific phono stage that is being used, and how gracefully it is able to handle RF frequencies, is usually the major determinant of what loading value is optimal for an LOMC. But I suspect that the uniquely low values of inductance and resistance of this cartridge, together with the mechanical aspects of its design, are likely to result in it being an exception to that general rule.

Good luck. Regards,

I've got an omtec cp-1 phono preamp and have to make myself a few rca loading plus for my dynavector mc (xx2 mkii) and have sent a mail to a firm in Germany who sell resistors..
They don't really get what I want and want me to tell them the loading capacity: from 10-100 ohms is what I want to try out, maybe a bit higher.. 
They also want me to tell them how many volts and what not these resistors should have.. they stunt me the following info and link :

Line 1 : We do not have these resistors in value of 80 and 90. I have filtered as much as possible according to customer's info.

We are unable to filter more as we don't know the tolerance need, the voltage rating and the power.

 

Please have the customer to review following in order to filter himself with his needs :

From what I have read on the net, a lot of people don't like/recommend carbon resistors, but metal foils.

Could you tell me what they want to know?

Any help would be nice, as I can't use the unit without these loading resistors ( the seller needed then for his new preamp and I had no direct contact with him...)

Thanks a bunch in advance
