Vintage Synth Repair

Hello,

   I own an arp omni 2, and the keyboard is not triggering correctly 
the notes. I have opened it and found that it uses little metal wires 
in each key in order to make contact with a bigger 'ground' bar.

The problem is that several keys have its wires missing and I can't 
seem to find such a metal with its flexibility and conductance near 
me.
I have heard that other arp keyboards from that time worked that way, 
so I thougt some of you might know which kind of metal do I need to 
repair it and where can I find it.


Thanks in advance,


Hardware_Mister.

Francisco,
You need replacement J-wires and they are a bit hard to find these days.

Try DB Musical Electronics - he's been selling Micromoog key board PCB's and
you can remove the J-Wires. He sometimes has auctions up on ebay in the US.

Some people have reportedly used Guitar strings to good effect - I'm haven't
tried it myself (since I keep some old scrap P-R keyboard parts for repairs)
but I think that an E or B string should work. Remember that these aren't
plated the same as original j-wires (some are gold plated) so you might have
to clean the contacts occasionally.

Thank you very much for your reply.

I have contacted them and asked for pricing of the
micromoog pcb.

I will keep you informed.

Regards,


Francisco.

Just curious, are you talking about using just the copper/brass that wraps
around the core string? I haven't had to replace j-wires yet but I do have a
couple that may need replaced some day.

thanks,

I used the unwrapped b or e strings .Can't remember what one.That was 1980ish.
  I do remember that at the time an ARP repair center told me to use guitar strings.

I too have used the guitar wire fix on my ARP Quadra, worked better 
than the Quarda did as a whole. Thank goodness ARP decided to put a 
hinge on the hood of that beast! Seems like I was under the hood 
fixing that mother more than my old '63 Plythmoth Valient! Bt when 
she worked.....ohh she was nice!
