Jelco SA-370h

Post by T.O.S. » 26 May 2019 21:55

Is this adaptable on Technics SL150/1500 ? it is longer (239mm) than the stock tonearm (230mm)

Hello,

It is the spindle to pivot distance that is important here. If you can mount the Jelco at its correct S2P distance, the effective length looks after itself. I'm not familiar with your Jelco; I have recently acquired a jelcoTK850 S. It has a slightly different effective length than yours, at 232 mm, so I can't say your S2P distance is the same as mine at 214mm. However, I did mount mine on a Rega platter; I just managed to fit it at the slightly shorter spindle to pivot distance and it worked fine. (Rega use 222mm) find out what disance your Jelco needs to be from the spindle and see if it can be accommodated by the Technics arm board. Usually you'll just need to elongate the hole for the original arm. It isn't hard to make up a plate to cover the plinth if the arm us too far away from the original geometry.

Mike.

The 370 should be mounted at 222mm, same as a Rega.

Cheers,
Alec

Didn't found an armboard for the 370 , just for the 750,550 ,850
It seems I should do a custom one if I'd get a 370h

You can use a Rega board. The hole for a Rega is bigger than you need. If you flip yhe arm base, it will fit into the hole. Use that to mark the positions for the screws.

Thank you , Alec !
I found online from a supplier on the ebay an arboard for 370h , so ,I could do that without much hassle .
But I am not shure if this tonearm is good enough comparing with :

a) Stock tonearm from SL-1500 MK1
b) SME 3009 II unimproved ( around 70-100 E pricier than the Jelco 370h) . Used , possibly necessary overhaul ( rubber gaskets , bearing).
c) Rega RB250 upgraded with stub and counterweight ( not so fond of , because the lack of removable headshell)
d) SME 3009 III if I decide to go with hight compliance carts (Grado Prestige Gold , Ortofon 2M Black ) - pricier 100 E over
Jelco 370h . Used ,possibly overhaul needed
e) Jelco 550 ,pricier about 125-140 E

The 370 is AFAIK the same arm as the Jelco/Sumiko Prestige MMT, of which I have 4, except for the cable being hard-wired.
I have had the Rega RB300 and the SME 300n II S2.
I prefer the Jelco.
It is light enough to do well with a Grace F-9 (which handily beats most any high compliance cartridge), but also does very well with a good MC cartridge. You can use heavier headshells to modify the effective mass.
It sounds better than an RB300 to my ears.
YMMV.

Cheers,
Alec

The ”hard wired” term what does it mean exactly ? I understand corectly that the wires are free in the tonearm base and they need to be soldered to an external phono cable ?
Such a female din plug could be used ? https://www.3345rpm.gr/en/product/5-pin ... connector/

The MMT has a DIN socket built into the bottom. The 370 does not.
What you link to is the plug for the end of the cable to the pre-amp, that would fit into such a socket.

Hi, I have a pair of the 370Hs and love them. Even more than the two Origin Live arms I have (very nice but PITA to change cartridges) The 370s fit a standard Rega distance. I did not have any problems fitting one on a Sota Moonbeam (it came with a Rega series 100). A major improvement. The ability to swap head shells is super. I have the other on a custom DIY direct drive TT. With either TT I have been able to track any cartridge I own (several) on all the tracks on the Analog Productions test LP. Everything from a Dynavector Karat23MR-RS, Denon DL 110, ADC XLM to Grado Sonato II. Easy to set up and simple to swap cartridges. I recommend an external VTF scale though as I don't think the calibrations on the counter weight are perfect. I also recommend the improved base available from the UK for them. It is sturdier and more precise than the OEM one. I don't recall the source right now, but it was a about $50. Well worth it IMO. If you can't find the source, post again and I'll look it up for you.

Note that the base for the 750 series will not fit, as the 750 pillar is thicker.

Cheers,
Alec
