Record Cleaning Machine ~ Ultrasonic vs. Rest
If the water bath in a US machine stays “clean”, doesn’t that suggest it’s not removing detritus from LPs, which is its purpose?  
Recommendations for MM Phono ~ Tube or Solid State
12AX7s provide plenty of gain but actually not much "drive". Drive is a term associated usually with current output, and the 12AX7 is puny in that department. In any case, gain is what you need and what you get with a 12AX7. Just as well you did n... 
Phono preamp or SUT for low output moving coil
Bill, I was just re-stating the existing bone of contention. In essence I agree with your position. Also, I took the Devil’s Advocate position in stating the argument for pinpoint RIAA accuracy, which is in my mind at least the idea that since the... 
Phono preamp or SUT for low output moving coil
The question or the argument is how accurate is accurate enough?  
Turntable hissing
Hiss is likely RFI, not a grouding problem per se.  Viridian's idea to short the unused inputs is worth a try.  But what the OP described as a hiss is later referred to by others as a buzz.  
Phono preamp or SUT for low output moving coil
Actually, you can change the load resistor in any MM stage to whatever value you prefer, if you can identify it and can solder.  
Phono preamp or SUT for low output moving coil
Herman, the word you omitted in describing the input impedance of the EMIA is “high”. The EMIA has a high input Z to facilitate using it with LOMC cartridges that work best into high-ish impedance, specifically cartridges that have high internal r... 
What Holiday Gifts did you ask for or Give to Yourself?
Mercedes Benz SLS Roadster, maybe.  
Garrard 301 - Project
Dover, I own the old QS preamp that has a built in MM phono stage, along with its linestage, not the newer models that I think are separates, a phono stage and a separate linestage.  Since I have measured the voltages across the tubes, and thereby...

Dover, Please lighten up. I was quoting Lalitk. That is why the words were in quotation marks.  Evidently Lalitk experiences the TFK ECC83 as tonally rich. As we all know, one's impressions of the SQ of any single item in a system are dependent up... 
Turntable mat for Sony PS-x6
You'll get as many different opinions as responses. I use Boston Audio graphite mats and also the SAEC SS300 metal mat, with good results on DD turntables like your PSX6. Anyway, you have the right idea about replacing the original mat, if it's th...

TFK ECC83s are so "legendary" for their "tonal richness" that the cost is high, and some duplicitous sellers are selling fakes. Caveat emptor.

Dover, who else besides Sovtek make “long plate spiral” 12AX7s and also market those tubes as LPS? But of course you can use any 12AX7/ECC83 in your phono stages.  
Phono preamp or SUT for low output moving coil
sgordo, I beg to differ; a SUT has everything to do with the impedance the cartridge will see. There is a direct mathematical correlation, in fact. And the more voltage gain afforded by a SUT, the lower the impedance seen by the cartridge, which w... 
Pass XP-17 and Hana ML loading question
I think SSG is saying he hears a big difference between 47K ohms load and any value equal to or less than 1000 ohms, where 47K sounds bad to his ears. I didn’t see where he talked about gain per se. So Karl, how do your Pass phono stages sound whe...
