Custom Arm Mounting Collar for Jelco SA-750 - essential for setting correct azimuth

[selfaddict]

Hugo you are the man .

I had the collar waiting for me when I came back home from work. Really quick delivery, cannot thank you enough .

The finish is outstanding and once I took the old original Jelco collar off the TT I realized how flimsy it really is. No wonder Koetsu uses much heavier collar in their tonearm, which is basically same as Jelco without the heavier collar and headshell.

It was the easiest upgrade I have ever made. There is no need for adjusting both sides of the tonearm pillar separately anymore, the centered collar screw will make sure the tonearm pillar is dead accurate just by tightening it, great

Great job and many thanks again. I cannot help sending few pictures of it. It
will work just perfectly with my black Jelco.

Hi Hugo,

Marco has just highlighted a minor problem with the collar, which applies to Technics SL-1200/1210 users who have the Sound HiFi armboard with the recessed centre section. The M6 grub screw is set too far into the collar to get the allen key in, without the allen key fouling the surrounding armboard and the Technics' chassis. The solution is simple - I shall get a load of longer M6 grub screws, which should mean that you will be able to use the short part of the allen key without difficulty and with no risk of fouling any adjacent part of the record player. The longer grub screws will be posted out to everyone pronto (eg tomorrow)!

No big deal - it'll be sorted with the longer grub screw

The arm collar is definitely a quality piece of kit and a major upgrade on the stock Jelco item!

Marco.

My apologies for this little niggle - I don't have a Technics any more so did not anticipate the problem.

I have the problem too


Thanks Hugo, see my comments about you in the buyers section in Private Exhibitions.

What a beautiful system you have

I have to try to keep wife happy , so she always has the final say what the kit looks like, but I have all the control how it sounds like

I do not know who has the upper hand, but I am very pleased of the overall synergy between different components. The last missing piece of the puzzle will be my new phono stage. Once phono stage is with me, that is the end of box swapping for a long time: Time just to enjoy that sweet, warm and fulfilling music that only valves can bring to us

I did PM you details yesterday and have sent another PM today. If you're not receiving the PMs, do let me know via this thread and I'll get Marco onto it.

Thanks for coming back, appreciated, hope I'm not too late for one of your Jelco collars? No, did not get your PM. I sent you one today?

If you still got one going put my name on it please and I'll send you the money?
Thanks

I am sending out longer grub screws today to those that need them. That should deal with the problem that Marco highlighted. Also, collars (with the longer grub screw fitted) are being sent to Vinylspinner, Bubba45 and Jazzbones.

Nice one - many thanks!

I've temporarily sorted the problem by sitting the T/T on its side, so I can get the Allen key in, and adjusting VTA in small increments, going back and forth that way until I got it bang on

I'll look forward to getting the longer grub screw though to prevent such a headache in future...

Later I'll be listening to see what the sonic effect of the new collar is, if any, and will report my thoughts here

Marco.
