| Who needs a MM cartridge type when we have MC? correction: I should have said, Both those directions are away from the pivot or cantilever line, not exactly toward the spindle. | |
| Who needs a MM cartridge type when we have MC? Lew, IMO the most elegant and concise description already supplied by J Carr:**What causes skating forces is the fact that, with offset-angle tonearms, the LP groove pulls the stylus in two vectors at once. One vector is from the stylus to the ton... | |
| Who needs a MM cartridge type when we have MC? That's what I was talking about regarding skating. The force will vary depending on position and stylus velocity. I think the idea is to find a setting where you get a centered cantilever at moderate velocity at different points on the record. Mos... | |
| Who needs a MM cartridge type when we have MC? From physics class:"Any motion in a curved path represents accelerated motion, and requires a force directed toward the center of curvature of the path. This force is called the centripetal force which means "center seeking" force. The force has t... | |
| Who needs a MM cartridge type when we have MC? Mike, nice to read about your recent experience with AS and your arms. As per Raul's request, your post was an empirical description of consequences or benefits. I took it for granted that the goal is to get a proper image and center. Bass perform... | |
| Who needs a MM cartridge type when we have MC? Hi Raul, Do you have experience with any Coral cartridges?Years ago I had an Adcom HOMC that I believe was made by them. The SAE 1000 is said to be there's also. I seem to remember something about a model 777?Thanks, | |
| Who needs a MM cartridge type when we have MC? Timeltel, Lewm, I wrote that as a practical guide for AS considerations, not as a physics lesson and repetition of everything that's been said. Apparently neither of you figured it out yet, because you're both only partially right. NO, centripetal... | |
| Who needs a MM cartridge type when we have MC? One thing I didn't describe well is alignment error consequences. The odd angle is in relation to the cartridge and cantilever. Although it's the tip that actually traces the groove, it's the movements of the cantilever that get the generator goin... | |
| Who needs a MM cartridge type when we have MC? Tangency and AS are two issues that impact on each other. If we agree that skating is caused by the additional vector from offset, then tangency becomes a separate but related issue. After all, a pivoting arm is only tangent to the groove at two p... | |
| Who needs a MM cartridge type when we have MC? Hi Mike, I completely believe everything you say. Obviously your fastidious and very into records and I didn't mean to discourage. It was only that picture as evidence of AS or wear, I took issue with. Most of us here are a bunch of guys outside o... | |
| Who needs a MM cartridge type when we have MC? Ecir, In the '80s I was the turntable guy at a busy high end shop. Sometime in the late '70s or early '80s, the owner purchased an Audio Technica stylus scope. This was sometime after the microline was introduced, I'm not exactly sure. It was an e... | |
| Who needs a MM cartridge type when we have MC? Lew, these forums are full of misinformation, but it seems like they're getting better. My understanding of AS was inaccurate until a tonearm designer and a couple of engineering types explained it. I like the story about the paddle and the river.... | |
| Who needs a MM cartridge type when we have MC? Ecir, the new pic looks like a normal stylus inspection view. Varying wear is easily seen, which is normal. The camera has nice resolution. With more magnification it would be a little easier for me to judge the amount of wear. With the AT scope t... | |
| Who needs a MM cartridge type when we have MC? Hi Ecir, Sorry, I just can't see it. Take a gander at this pic of a microline. It looks the same as a microridge.http://www.vinylengine.com/library/audio-technica/cartridge-guide.shtmlYou're looking at the front of the stylus. In the pic you linke... | |
| Who needs a MM cartridge type when we have MC? Hi Ecir, Mike, I looked at the photo of the microridge tip and it appears that the front and back surfaces are illuminated, rather than the sides. What is that ridge perpendicular to the lighted surfaces? The ridge should run side to side above th... |
