Some thoughts on dust covers
So I have a question for those of us who advocate using a dust cover during play, for the primary reason to avoid the accumulation of dust. (The acoustic argument is different, I think.)  Let’s assume we all agree there is some sense to using a du... 
Some thoughts on dust covers
The ELP is not immune to dust, IIRC. TJ, if you want to come over and digitize my 3000 LPs, you’re welcome if you bring the necessary gear.  
Some thoughts on dust covers
.."My deduction was that ambient sound feedback from the listening room and speakers is significant and audible.." But it's fair to say that you don't stomp around and shout out while actually listening to music. Nor do you use a buzz saw, etc. C... 
Some thoughts on dust covers
There is no correct answer. No corporation or engineer can give you the correct answer. Do what makes you feel good, but I’d advise against scolding others who do not see the issue in the same light as you (meaning any of us).  
Some thoughts on dust covers
Here comes a bunch of comments and testimonials about dust covers, up or down, good or bad. I only suggest that each individual needs to try it both ways (or each of the 3 possible alternatives, up, down, or off the turntable during play). As I’ve... 
What preamp with both line stage and phono?
Just about any phonolinestage, other than those Shindo units, ought to have an output impedance far lower than 5000 ohms, which is quite high.  In addition, you might consult with the manufacturer(s) of an amplifier with an input Z of less than 50... 
Fidelity Research FRT-4 and Entre ET-100 step-up transformer SUT comparison
I believe what you guys say, but see photos here. https://www.google.com/search?q=fidelity%20research%20frt4%20review&ie=utf-8&oe=utf-8&client=firefox-b-1-m In the review I read, the reviewer said he found the 18K resistor when he op... 
Fidelity Research FRT-4 and Entre ET-100 step-up transformer SUT comparison
The mention that the FRT4 has its own leads (presumably from its outputs to the phono inputs), stimulated me to learn more about it, because the claim led me to believe the FRT4 might bear "flying leads" at its outputs. That means that the interco... 
Seeking opinions on the Luxman PD151 and EQ500 combination
"wide channel separation and tight channel balance are cartridge performance measurements directly relating to good/better/best capability". Perhaps, but the numbers quoted by manufacturers are for an average sample when brand new. There is no gua... 
Second hand record turntable - Which one?
You’d be fortunate to find someone competent and honest enough to do all the testing that Bill recommends, and if this rare individual is in the audio business, the cost of those services is likely to double or more than double the base cost of th... 
Seeking opinions on the Luxman PD151 and EQ500 combination
Just so you know, I am not an advocate of dust covers except to keep dust off the platter when the TT is not in use. When playing LPs, my dust cover(s) are somewhere else in the room, never on the TT or over the LP. This is because I think a close... 
Second hand record turntable - Which one?
The way I think of it, there are two reasons to buy a used TT. One is to save money over the cost of a new sample of the TT you seek, and the other is because the TT you most want to own is no longer in production. The TTs you list are inexpensive... 
Victor tt-101
I’ve had my TT101 platter off no more than 2 years ago and yet it’s pretty frozen to the spindle. Perhaps pressing down on spindle while lifting the platter would actually work. Without the need for a mallet, that is.  
Rays Tubes
Whoops! I just googled Billington out of my own curiosity.  To my surprise, the business is still in operation. I don't know whether their Chinese made 12AT7 (which went by another alphanumeric designation, as I recall) is still available.  
Rays Tubes
My Atmasphere monoblocks originally used 12AT7s as input tubes, which means they were responsible for most of the voltage gain across the whole circuit. At that time, I purchased a wide variety of different brands of 12AT7, to determine which soun...
