I'm into amateur sound recordings using electret microphones. These require
a low voltage, ~ 2.2v, which is supplied by the camcorder or Minidisc
recorder via the signal lead. Consequently for low noise recordings it is
essential that the 3.5mm plugs and sockets between the microphone and
recorder aren't suffering from handling noise caused by oxide on the
contacts. Where possible I've obtained gold-plated plugs from headphone
leads, but the choice on offer* doesn't cover my precise configuration, and
I do get handling noise.
(*I've looked at CPC-Farnell, Maplin & RS websites recently.)
Can anyone recommend a UK based gold plating service which might be able to
plate the nickel(?) coated plugs and sockets which I can obtain easily. And
at a reasonable price for very small numbers.
Thanks in adavance

I'm just wondering whether what you need is a low-noise cable, rather
than gold-plated plugs - something like RS stock no. 367-296, perhaps.

How about a soldering iron. Just solder the wires on each time - it'll
be better than any connector.

Slightly inconvenient and may not cure the problem if is is due to cable
microphony. Good to do once though to prove the point one way or the other.
