Resistor in phono stage

I certainly agree about the (subtle) effects of resistors and capacitors, in any circuit, but in this case the issue of cartridge loading, if it were to be an issue, is dominant over parts quality, in my opinion.  Once you skew the frequency response, boutique parts are not going to fix that (unless you also change values to correct the frequency response).

Al, Thanks for the correction, my bad.  Thanks also for giving me the easy way out. I was plain wrong, but it was due to brain fart.

Misternice, there are some who say that any MC should work fine into a 47K ohm load, and there are others who load down MC cartridges (which is to say they load the cartridge with a lower resistance) and swear that their choice is superior.  In principle, there is no right or wrong.  I only recently experimented with 47K as a load on some very low output MC cartridges, and I find that I cannot go back to the 100 ohm load that I previously favored.  The sound is just more open and effortless, in my system, with my cartridges and phono stage.  Ralph Karsten has pointed out that the phono stage itself is most affected by the load resistance; the cartridge doesn't care much until you get down to very low resistance loads, where now you are losing signal voltage to ground.  That reduces gain, and to my ears seems to roll off treble, both of which phenomena make electrical sense.

A wild card in your equation is the fact that you stored the cartridge for 6 years.  That may have affected compliance.  Give the cartridge several dozens of hours to loosen up before making critical judgements.

Vinyl Engine says that your Sumiko has 11g effective mass, with the "L" weight.  I found some comments on the internet to the effect that the Supex "likes" a high mass tonearm, which the Sumiko is not.  (11g is in the low range of "medium" effective mass.) Maybe that is a source of your dissatisfaction.  But I would do nothing until the cartridge has had a chance to break in.

Thanks, mofi. What I see is a description of how to wire resistors (and/or capacitors) so they end up in parallel with the input, which will effectively lower the input resistance (and/or raise the input capacitance).  Thus, the end user can achieve nearly any resistance desired, below 47K. (Resistors wired in parallel will always result in a net value lower than that of the highest value of any one of the resistors.)  Adding a capacitor in parallel, using those same binding posts provided, will raise the total capacitance, since capacitors in parallel are additive in value.  (Pardon me if you already know this.)

But meantime, the OP seems to have lost interest in his own question. Which is fine.

Mofi, baby.  Thanks for the info on the PH3SE. Of course you CAN change the 47K load resistor by directly de-soldering it, removing it from the circuit, and replacing it with another resistor of preferred value.  Many listeners prefer a 100K load resistor for most MM cartridges. (See the thread on MM cartridges.)  Anyway, I think you must have misspoke by suggesting you can change capacitance by changing the load resistor. No problemo.

Certainly, 47K cannot be regarded as the "wrong" resistor for an MM. We now need to know what cartridge the OP is using and whether he is using a SUT between the phono and the cartridge. Etc.

What do you mean by "wrong resistor"?
What cartridge(s) are you using, and by what criterion do you think the load resistor is wrong?  If you have an ohmmeter, just stick one probe into the RCA phono input jack and place the other probe on the outer barrel of the RCA jack; the resistance thus measured will be the value of the load resistor, unless there is a SUT in the signal path.  I don't know what the value should be for the PH3se.  The standard for MM cartridges is 47K ohms.  MC cartridges typically are run with more of a load (meaning a lower value of load resistance, down to around 100 ohms in some cases).
