[sdiy] soldering bananas

[Theo]

Hi Ruud
Please _DONOT_ and I mean _NOT_ ever use S39 for electric stuff.
After a while the S39 will cause corrosion of whatever copper it comes in contact with.
When there is a current going this process will only be quicker.
S39 is for use in plumbing and the like only, even then its best to clean (wash) the remaining S39 up.

As for you going bananas, it might be a heat problem. 
The banana jack has a lot of metal, 
so the place you try to solder may cool down quicker than your iron can deliver the heat. 
If your have a solder station turn it up or try using a solder gun.

A other solution is to use a solder ring.
This is a little ring with a solder lip.
You solder the cable to the lip, 
then mount the bananajack with the ring under the nut.

HTH
Theo

  mornin',

  working on my new synth, i came across this weird problem. i'm having a hell of a time soldering my banana inputs. it just seems the solder won't stick to it, sometimes i can pull the wire right off. i'vew used differenmt types of solder, with and without s-39, cleaned the things with 96% proof alcohol first to remive any grease, etc. 
  i'm a little baffled, i've soldered jacks and all kinds of other stuff for 20 plus years and have never had this happen. any ideas from you people who work a lot with bananas? 

  thanks!
