jelco 750D kick off!
thanxs everybody that encouraged me for it. Very happy, at least this is the impression after few spins of vinyl.
Its a musical tonearm and in crescendo stays uncompressed and do not mix it up intruments. Very nice.
Now, what the hell shall i do with the damping oil? Read somewhere to put three drops only, in other places i read no nedd. Whats the best intake on this? Thanx

Hi Daniele,
Glad that the Jelco is hitting the spot for you. It's an excellent tonearm, which performs far in excess of its price tag! As for the damping oil, just put a few drops in (NO MORE), as the effect will improve the performance of most cartridges.
Put too much in, and it will KILL the sound - and getting the oil out afterwards is a rather more difficult process than putting it in!!

I have not experimented 'with' vs 'without' on my Jelco. A starting point would be to follow the follow the guidance in the manual. If you did not get this Arm new there is a manual available at http://www.vinylengine.com/library/jelco/sa-750d.shtml

Surely the answer is going to depend on the cartridge fitted. As a broad general rule don't add damping if you don't have to. The arm has quite a high effective mass and so should naturally work best with relatively low compliance moving coil cartridges. If you want to use it with a v15 then you may need some damping.

That makes sense, Richard. However, I listened to the 'before & after' effects of adding damping oil to the Jelco, using a DL-103 as a reference (a cartridge that one could argue wouldn't benefit from damping), and adding a few drops of fluid definitely improved the performance of the tonearm and cartridge
You mustn't overdo it, though!!

Universal approach
Being pragmatic.....as it seems impossible to remove the oil when there, it makes sense to use a universal approach that can fit the majority of carts that would be used in the Jelco lifetime.
I have a Goldring 2400 currently and with test record I got 11 Hz resonance. I think it is acceptable per se....
By the way....I had addressed once more the Jelco mass value with Huchida san. I was explaining that there are several different values, depending from the forum and I asked him the true value of mass. You guess what?
13,48 gr only!

Indeed, but that all depends on what headshell is fitted to it!

i suppose he considered the standard headshell
Is it not the case? And if not always, how much is the weight of the standard headshell giving the figure 13.48gr? So I can put it over my spaghetti weighter and will know my case with precision....................." Hey my dear, a strange object is floating in the spaghetti bowl, any clue?"

Lol......
Yes, he'll have arrived at that figure using the stock headshell as a reference. However, the point I was making was that one can adjust the effective mass of the Jelco simply by fitting a lighter or heavier headshell.
That's the beauty of detachable headshell arms (plus, fitting cartridges is a damn sight easier, too)!

Marco, do you have the standard headshell figure?
Just to make sure i have the standard one...Sometimes packing error might arise?Although in my experience Japanese friends are extremely precise in whatever they do as a business
