Paul,

I use 3.5mm plugs and sockets for recording bat detectors becaues that
is how they are wired. I use 10 metre extension leads rather then
permanently long leads but the problem is that these plugs and RCA
plugs can easily pull out. The answer with a junction on an extension
lead is to tie a half knot at the joins so the plugs pull togeher
rather than apart.

If you use long leads for stereo or two track like my bat detectors
you can get a bit of cross-talk from a combined cable. I either use
individually screened conductors or figure-8 twin screened cable.

My soldering tip again - use extra flux when soldering delicate
components and you can do the joint almost instantly. Most components
allow for a second or two soldering time.
