| Tube Tester Agree with Viridian that you want a tester that measures transconductance. And that usually means Hickok or B&K (often made by Hickok.) Transconductance of a given tube varies with plate voltage and current. Unfortunately very few vintage test... | |

| How are you playing your precious MONO Vinyl? My point is that the absence of a Microgroove label on a post-1948 LP does not necessarily mean the LP doesn’t use the 0.7mil groove width. | |
| How are you playing your precious MONO Vinyl? “Microgroove” was likely a patented trade name, which is probably why you don’t see that exact word on all mono LPs dating from 1948 or later. Perhaps not all labels were licensed to use that term. | |
| How are you playing your precious MONO Vinyl? Read the Miyajima website on w hy they offer cartridges with 1.0 mil styli. But keep in mind they’re trying to sell those cartridges. | |
| SUT Interconnects Yeah, sure. If it makes you happy. The first thing I said is that the dielectric can affect capacitance. As to your other point, what temperatures do you have in mind,given that most of us maintain our listening rooms at between 66 and 72 degrees ... | |
| How are you playing your precious MONO Vinyl? Because it makes very little difference UNLESS you play mono with a 1.0mil stylus, I would guess. In that case there may be a slight issue with playing the micro groove, loss of extreme treble. Maybe not a big deal. | |
| How are you playing your precious MONO Vinyl? Bill, my experience is entire different from yours. Most MC cartridges do not accurately reproduce piano in either of my systems. My Koetsu Urushi and Ortofon M2000 being notable exceptions. The others are inferior to my best MMs and MIs in reprod... | |
| How are you playing your precious MONO Vinyl? I only said “high mileage “. Was thinking >100,000 miles. Of course different engines react differently. I would not follow Elliot’s advice with a new or near new car. Plus, I’m not a BMW guy. | |
| SUT Interconnects I think that bit of double talk refers to the dielectric effect. Different dielectrics ( insulation) will affect the capacitance of the cable which in turn affects frequency response. Same goes for the spacing between the conductors and the geomet... | |
| How are you playing your precious MONO Vinyl? High mileage cars tend to lose a little compression and therefore lose the requirement for high octane fuel. I don’t know whether this applies to Elliot’s report or not. | |
| SUT Interconnects No, westcoast, capacitance does not change with frequency. What you are thinking about is that because of capacitance, impedance changes with frequency. (Impedance of a capacitor is infinite at DC and goes down as frequency goes up, by an amount... | |
| How are you playing your precious MONO Vinyl? Sorry, Doggie, I was editing my post while you submitted yours. Ortofon's use of the term "dual coil mono" sounds like the kind of double talk I read when I researched the Quintet mono. In other words, it sounds like code for a bridged stereo cart... | |
| How are you playing your precious MONO Vinyl? The difference between what we are calling a true mono cartridge and a stereo cartridge that has been bridged to produce a mono signal in both channels is presumably that the true mono cartridge has had one of the pair of coils that serve each cha... | |
| How are you playing your precious MONO Vinyl? Here’s a question. Suppose you have a mono cartridge but don’t know whether it’s a true mono or a bridged stereo type. How would you tell the difference? |
