If NOS pre or power tubes became unavailable altogether, what new tubes would you buy?
The very best 12AU7s I have heard in my system were supposedly selected 12AU7s that were made in China.  I bought them from Billington in England, and they were "Billington Gold" class.  The only drawback was a relatively short lifespan compared t... 
Fidelity Research FR-64 vs. FR-54
Raul, My source for the notion that you use the MAT02 in your preamplifier is.... you.  You told me this in a personal email a few years ago.  In the same email, you in effect congratulated me for choosing it. Or perhaps I misunderstood you; perha... 
Audio Technica ART9 sounds awful
Just a last gasp:  The source of a phase issue (one channel out of phase with the other), if there is a phase issue, need not be limited to the connections of the color-coded leads at the cartridge; it could be downstream at any junction.  It coul... 
Fidelity Research FR-64 vs. FR-54
Raul, Did you read my post from 3 PM today? In that post, I acknowledged that solid state devices can be put to good use in audio. Yes, the quote from the IEEE is an old one; I may even have posted it once before. When I come down adamantly on the... 
My personal experience with Direct Drive versus Belt Drive
Humans have inertia, too.  Just like massive plinths. 
My personal experience with Direct Drive versus Belt Drive
If the plinth is very massive, then I would think Rollerblocks would be good.  With a torque-y motor like the one in the Mk2, the force spinning the platter in the clockwise direction also creates a counter-force that "wants" to rotate the plinth ... 
Fidelity Research FR-64 vs. FR-54
Just to be clear, by tweaking Raul for his nearly crazy hatred of tubes, I do not mean to imply a similar negative bias against transistors. Perhaps I went too far in that direction, in order to get Raul's goat. (Raul, there must be an equivalent ...

They say it's "simple physics".  Simple physics tells me that a small wooden disc is too small to do much of what they claim their discs do in the context of an entire room full of larger objects and audio equipment.  It's a matter of mass.  We ne... 
My personal experience with Direct Drive versus Belt Drive
Multiple motors. What would interest me to try, if I was still interested in belt drive for my own use, would be two motors positioned at opposite sides of the platter, 180 degrees apart, so as to equalize the forces involved in rotating the platt...

What do they do, is what I meant. I have never understood how a little piece of wood, or even many little pieces of wood, could be expected to "do" much to tame room acoustics or dampen chassis resonance, one of those two of which I presume is the...

Define "work", as in "they work great".  Someone. 
Lloyd Walker's Next Shocker
Sbank, What do you use as a cleaning solution in your ultrasonic cleaner, pure water or something else?  Thanks.For me, the major advantage of an ultrasonic cleaner would be the capacity to do several LPs at once and on both sides at once.  I thin... 
My personal experience with Direct Drive versus Belt Drive
Has2be, I don’t disagree with the substance of what you wrote, but I am a bit puzzled by the following phrase: "at a time when everyone was dumping belt to manufacture DD because the electronic end was at a rabid pace of growth and precision and y... 
Pani ... New ART-9 up and running ...
Thanks for that review.  I own a first generation ZYX Universe with low hours on it, and I just bought an ART7.  I plan to compare those two, and if anyone is interested, I will report here.  The ART7 is very different from the ART9 in terms of co... 
Dear wise-folk, turntable motor grinding after oiling?
I would take it apart again and clean both the male and female parts of the bearing, as best you can using lens paper and maybe some pure alcohol. (I prefer photo lens paper, because it does not fragment and leave scraps buried in the bearing well...
