Pass XP-17 and Hana ML loading question
Also check the leads at the cartridge as Atmasphere suggested and even though you say you’re relatively happy when load R is 1K or less. So this is a real shot in the dark. Color code as follows: red= right channel hot green = R channel ground ... 
Pass XP-17 and Hana ML loading question
Until now, you never revealed that both the XP 15 and the XP 17 had this sonic character when you set the load to 47K ohms. Since you used the term “amps”, is it correct to assume that you mean both phono stages? If so, I am stumped, because it is... 
Pass XP-17 and Hana ML loading question
Which is what I said, too. But it can’t be at the cartridge because he reports relatively good results with all other choices of load R. Which is why I suggested there may be a phase error incurred in relation to wiring of the load selector switch... 
Pass XP-17 and Hana ML loading question
One remote possibility: when you set load at 47K, the two channels are out of phase with each other. That would have to be due to a glitch in the internal wiring of that resistor, since other loads are at least functional. I would consider sending... 
Something new.
Junk. And I think off the market because of some nasty accidents.  
Pass XP-17 and Hana ML loading question
Have you tried a 47K ohm load with any other typical LOMC cartridge, ever, with either of the two Pass phono stages?  What was the result?  Thx.  Also, can you define "terrible"?  Do you mean that the treble was rolled off or missing, as you menti... 
Pass XP-17 and Hana ML loading question
You are not the only one who reports the result that changing the load resistance by 20,30, 40 ohms in the already low resistance region (say, below 1000 ohms) makes a critical difference, with a LOMC cartridge. All I can say is, I never have unde...

There’s absolutely no way that loading an MC with 47K should eradicate treble. That’s very odd.

Mistracking.  
Why I don't hear bass drums on Jazz LPs?
Found this 2LP set in my collection, “The Big Beat” on Milestone. Features Blakey, Roach, Elvin Jones, and Philly Joe Jones , in separate sets recorded in the late 50s/early 60s. Listening to Elvin now. Each group is replete with some of the great... 
Mainstream Phono Stages Incorporating Premium Branded PCB Parts - Do They Exist?
I used to frequent the store on rte 123. Vu is a nice guy. But his shtick (tube SE amps driving hyper-efficient electromagnetic speakers)and my shtick (OTLs with ESLs) are very different. He used to have a Russian guy who built those custom SE am...

Ok. Then play with the values. You can’t damage anything.  
Pass XP-17 and Hana ML loading question
As Atmasphere is fond of reminding us, the phono load resistor is for the phono stage. Anyway, in my personal experience of playing with load resistors, the value makes very little difference. Of course, there are others who have had contrary resu...

Larry, are you talking about DeJaVu Audio in northern Virginia? $400 capacitor? Indeed.  
Mainstream Phono Stages Incorporating Premium Branded PCB Parts - Do They Exist?
Pindac, if you are referring to copper foil in oil capacitors, especially those marketed under the Jansen (sp?) or AN name, I have found them to be unreliable when asked to tolerate voltages that are "high" in a tube circuit, but well within their...
