Glanz moving magnet cartridges
Thanks for the in depth explanation. What I fear is that the suspension has gone bad, but then I wonder why the same would have happened on two samples. Certainly that’s not impossible. I’ll see what I can find for a reasonable cost. Given the mys... 
Cartridge incompatibility, Soundsmith and Luxman
Obviously you know nothing about quality resistors. Vishay is a big company, and they make dozens of different types of resistors, much like Caddock. So not all Vishay resistors are created equal. One might debate the need for or an expensive nude...

Tomic, your point, other than the notion about personal preference, is lost on me. Can you be more explicit? Do you really not know what comes after the load R? I’m guessing that was rhetorical.

Thanks, Dover, and thanks, dgob, for your suggestions. I hadn’t expanded my horizons in the search for a repair much beyond the continental USA. Maybe I should do so. Dover I confess I don’t understand your suggestion regarding a donor. I do have ... 
Decided to try a SPU cartridge
A SUT converts voltage into more voltage (Jason), at the expense of current, which is only one reason it would be nonsensical to drive a current driven MC section from a SUT.

The finest Vishay nude resistor costs more like $13. Caddock TF030 costs about $7 each and is nearly as good, maybe indistinguishable. For phono loading, quality counts but the watt requirement is tiny. The change in load resistance is compatible ...

If the OP wants to sell his Zephyr cartridge, I am interested. Just saying. I don’t advise it, but I’m interested.

That's for sure. If he wants to let the tail (the 100 ohm resistors) wag the dog, then he must acquire a LOMC with typical LOMC inductance.  But also gain must be high enough to work well with the inherent gain of the MC section (plus the linestag...

Larry, The low output Zephyr already has a low internal DCR of 10 ohms.  That's not the problem.  The problem is its inductance, which, at 2.5mH, is about mid way between a typical LOMC (about 50 microhenries) and a typical MM (500 millihenries, o... 
Cartridge incompatibility, Soundsmith and Luxman
Larry, If you read the responses, you will know that the problem is almost certainly the fact that the fixed value of the load resistance at the phono inputs of the Luxman is 100 ohms.  The Zephyr is a rare low output MI type, which has high induc...

Changing the phono load resistors is neither a mod nor a tweak in my book. But why do you hold the opinion it shouldn’t be done?  
Thoughts on the various platter materials used in Pro-Ject's midrange turntables?
He’d have to buy two turntables to try two different platters.

Dgob or Raul or anyone, last year I picked up a defective MF2500. It plays music but sounds strident, shrill, and distorted. Andy Kim more or less declined to work on it, either because he didn’t feel it was worth the cost of his effort or because... 
Thoughts on the various platter materials used in Pro-Ject's midrange turntables?
I think I was a little too emphatic in my statement about Pro-ject. They seem to have many satisfied users. I am no expert on mid or low cost belt drive TTs.  
Thoughts on the various platter materials used in Pro-Ject's midrange turntables?
Using 3 different materials on 3 different models from one company indicates the absence of any coherent theory at Pro-ject. So I wouldn’t buy a Pro-ject at all. You don’t say whether any or all of these come with a mat. Aluminum platter with mat ...
