Effective Length of Jelco SA-750D not the same as Rega tonearms. - B.K. 07:37:29 01/17/10 (1)

Correct. The SA-370H is the same as the RB-250/300. (see below). /nt\ - Opus 104 07:53:17 01/17/10 (0)

How much do you want to spend on a new arm? nt - olddude55 07:33:10 01/17/10 (2)

Not too much, certainly less than $500 -nt - AbeCollins 10:10:51 01/17/10 (1)

In that price range - olddude55 10:19:48 01/17/10 (0)

Abe, the Jelco SA-370H uses the same mounting geometry as the Rega 250/300 - Opus 104 05:20:36 01/17/10 (7)

Question for Opus 104.... or others - AbeCollins 12:12:17 01/17/10 (5)

IMO, I'd have Kevin do a Cardas re-wire on the Technics arm. - Opus 104 13:36:42 01/17/10 (0)

Suspect Jelco specs and geometry - hesson11 05:04:03 01/17/10 (36)

Nothing suspect about their tonearm dimensions - B.K. 05:15:53 01/17/10 (35)

all due respect - you and Jelco are wrong ... - VynylTap 19:55:42 01/17/10 (25)

YOUR OWN numbers provide the answer to your question. - B.K. 02:49:36 01/18/10 (22)

What are you talking about??? No, no, no. - VynylTap 12:10:41 01/18/10 (21)

Then stop wasting your (and my) time here. - B.K. 15:00:59 01/18/10 (20)

I'm done. Buy the arm. Actually mount it at 214 mm and then get back to me. - VynylTap 20:12:01 01/18/10 (1)

You are done, because your whole arguemnt is without basis. - B.K. 00:29:11 01/19/10 (0)

Beautiful. Different arm. (nt - good grief) - VynylTap 20:14:28 01/18/10 (3)

Are you setting out to demonstrate that you are IMPERVIOUS to logic? - B.K. 00:47:35 01/19/10 (2)

It's a different arm with a different effective length!!! That's not a 750D is it? - VynylTap 14:16:36 01/19/10 (1)

You'd think! - hesson11 08:43:06 01/17/10 (8)

The tonearm headshells have extra long slots - B.K. 09:37:44 01/17/10 (7)

With the arm mounted at 214mm and 66/120.9 null points - VynylTap 20:13:06 01/17/10 (4)

In your original post, you didn't show that the effective length was not equal to 229mm. - B.K. 03:05:06 01/18/10 (3)

you're reading the post wrong - I clearly say it's 232mm. - VynylTap 12:15:40 01/18/10 (2)

No, YOU are READING badly. - B.K. 00:49:56 01/19/10 (1)
