Hi, I am constantly trying things and once in a while come across something that has better than average performance in its price range. I bought two of the 370H tone arms. They are "S" shaped with standard removable head shells. Unipivot design with damping. The only issue is that they are 9.5 inches long (like Rega and Origin Live) and may require modifications to some turntables as many are only 9 inches in length (yes I know that there are 12s, 10s, 8.5s and others too). Since all my turntables were made to handle Rega arms it was a no brainier. The arms are on the lower side of middle mass ones but work fine with everything I own. Tracking is excellent, set up is easy. They have on the fly anti skating, and are adjustable for height and damping (or none if you choose). A good buy at currently $300 on the web. You will need to spend at least twice that to do better.

Good listening
Bruce

Bruce looks good and in the same price range as a Rega 300 arm. I wouldn't consider them a "S" shape though. Not that that is critical. I love removable headshell as you roll carts. in seconds.

Hi Mark, actually a "J" shaped arm. I wasn't thinking as I wrote. Here they are nearly $150 cheaper than the 300 series Regas. I like it better than the Origin Live arms I have. The OL arms are lighter in mass and do not have removable head shells, no on the fly anti skating and are harder to set up right. But they do work better with highly compliant cartridges. One surprise is that the Dyna Vector Karat I have seems to do better in the Jelco than in the OLs. The Grado woodie is better in the OL. Go figure.

A bit OT (since I started it I guess I can take some liberty). I now set up the tracking force and anti skating with a dual trace scope and a test LP. It is very clear on the scope if miss tracking occurs. When it does...just adjust either the VTF or AS to compensate. It works like a charm. Usually if both channels have issues it is VTF, if only one then AS.

Good listening
Bruce

There was a very nice looking P7 for sale in Oz. but in another state. Only 4 years old with little use. I would have purchased it if it were local.

A good tonearm with a long history going back to the Sumiko MMT. It's not a unipivot though, Jelco arms use their patented single point cross cross suspension system.
