Outer Vinyl Sleeves, is it a good idea?
Mold is everywhere. whart, because of semantic differences among words like “sleeve”, “envelope”, “jacket”, and “cover”, I am not really sure what it is you do, but anything that reduces the static charge that results from removing a vinyl LP fro... 
Outer Vinyl Sleeves, is it a good idea?
Nothing but a nuisance in my opinion. If you own a thousand or more LPs, do you mean to tell me you don’t want to risk wear on the album cover from pulling an album out of a record rack? If so, that means you’re likely playing only a select few LP... 
Mono Cartridge Stylus
Bach's work is in my mind the forerunner of modern jazz piano music (Brubeck, Peterson, Powell, Monk, Walton, Evans, etc).  Which is to say that any cartridge that does well with Bach ought also to sound good with piano jazz LPs. Don'tcha think?

Flabby bass is about damping factor as much as anything else. Don’t expect a tube  amplifier to drive a 4 ohm woofer without “flab”.

Last time I tried to play LPs while stoned, which was only several months ago, I had to stop the session for fear of damaging my cartridge or scratching a beloved LP, or both. My hand-eye coordination was very impaired and/or I didn’t care.

Phase splitter is usually done by driver tube and is better done by a 12AU7 than by a 12AX7, but anything is possible. A tube that has cathode and plate resistors of equal value, classically 47K ohms, is the phase splitter. But there are other way...

12AU7 is probably used as a driver tube, which means it adds no gain and probably has little effect on SQ.  However, in my experience, there is no such thing as a good sounding 12AU7.  I replace them with 12FQ7 or 6FQ7 (depending on the available ...

You need to get hold of the plate curves for the two tube types. That’s a graph displaying plate current vs plate voltage with separate curves for each bias setting displayed on that background. See how they compare.Then make some measurements of ...

Did it work “great”, or was it just a successful marketing phenomenon at a time when there was no serious competition?

As I recall, it was odorless, which means it had to be quite dilute, if it contained alcohol. Or that any alcohol had evaporated by the time I took a whiff.

Among audiophiles I knew back in Diskwasher days, more that a few thought the fluid was just water or very diluted alcohol at best. What’s the inside scoop on that?  
Will a record weight harm the motor in a direct drive turntable?
Aldo, I own an L07D and the record weight that optionally came with it. I’d guess it weighs 250g, tops. I also use it on a Victor TT101 and on my Lenco which has a massive aftermarket bearing. But the problem is when you get up over 500g or even m... 
fozgometer v2
Please correct me if I’m wrong. I’m sure the foz works as advertised to equalize crosstalk. But what I and others have said is that in doing so, the stylus tip in many cases will end up slightly askew with respect to the groove, unless the coils a... 
fozgometer v2
Do you really anticipate that you’ll only align one cartridge for the rest of your life? Anyway, in my opinion you don’t need a fozgometer. Just set azimuth so the stylus tip sits symmetrical to the groove walls, which almost always means set azim... 
Phono Stage - The great analog tragedy
For me, the most consistent difference between home audio and real life is dynamics. The most convincing demonstration of that was having a sax played live in my listening room, with the musician standing between the speakers. Wow!
