Some thoughts on dust covers
I can't resist. Too much idle time. The equations of Newton and Coulomb are quite adequate for considering the situation at hand.  You used their constants yourself as a basis for your statement about the relative magnitude of the two forces. No n...

RB, to the question contained in your last paragraph, my current opinion, open to change if presented with contrary data (not a “belief”), is based on my data, the testimony of another Forum member who’s done the experiment many times before me wi...

The ES force is determined by Coulomb’s law, which like Newton’s equation for the gravitational force is an inverse square law. Both forces are inversely related to the square of the distance between the two objects under consideration . The diffe...

Richard, please get over yourself. I did believe what Shure wrote because of who they were, a company with high integrity and a scientific approach that they adhered to by backing up the majority of their information with decent experiments and by...

Dover is correct that Shure do not describe the experiment that led to their saying static charge due to the stylus is negligible. My own frustration with that lack of detail is what led me to buy a static charge meter and do the experiment myself...

Dear RB, Googles AI is full of.... baloney as regards bullet number one, and the whole business of AI is scary, because we tend to believe ""AI" and AI is nothing but a computer that scanned a bunch of opinions put into print by humans, and human...

Wyoboy, I feel compelled to correct incorrect information that falls within my range of knowledge. Ideally, the information on this site should be as accurate as possible, because some of these posts are read and believed by newcomers to the hobby...

Good way to look at it, grk. Schroeder firmly constrains the pendulum motion with magnets, which effectively moves the pendulum's pivot down to the junction of string and arm wand.

Just for fun, I looked up the characteristics of the 6N1P and compared them to those of the 6922. First, they are compatible, meaning a socket wired for one will work for the other. Both have a gain factor (mu) of 33, so no difference there. Howev...

He was known in New Haven as the "Rear Admiral".  True.

"Prima facie it seems that when you played your record, it doubled the charge" First, 0.1kV to 0.2kV is a range where the meter is not very accurate and readings are not very repeatable.  The meter never reads zero, for example. So the difference ... 
What should I look for when purchasing a quality album?
My dad was a proctologist, so I'm cool with it. Every year I attend the Capitol Audio Fest, and I usually buy 8-10 LPs from my favorite vendor, at prices up to $20 but usually about $10 each. However, the experience gives me the chance to see wha... 
What should I look for when purchasing a quality album?
Goldmine is fine as a guide to estimating condition, but some of the $ values they place on some LPs strike me as ridiculous (too high). That gives sellers the cache' to ask high prices using Goldmine as a reference.

thecarp, Sorry I misconstrued your earlier post. I grew up in New Haven, and my wife is from Deep River. Although I live in MD near DC, we visit CT fairly often. Can you divulge the name of the record store in Mystic?  Not that I am much of a buye...

It’s an ingenious pivot, but it is a pivot. What’s so wrong with calling it a pivot? By all accounts Schroeder tonearms are among the best.
