[Elecraft] Tororids

Al and/or Dianne,

If you have a Hakko-style soldering pump similar to the Model 808, its nozzle (ordinarily used for desoldering) makes a great way to heat and apply solder to the varnished leads to remove varnish and tin them quickly. 

Prior to using that technique (recently suggested on this reflector),  I used a combination of candle or butane- lighter flame, fine-grit sandpaper and an occasional light coating of flux to get the job done to my satisfaction.

Whatever method you adopt just be sure that the finished solder joints are completed with a proper "wet" look, and measure their resistance to the PCB board. Obviously, be sure to remove any residual traces of flux that may remain behind too.

        I'm having trouble tinning my toroid leads. In spite 
      of rigorous cleaning they just don't want to accept
      solder ( Kester 44 ). Will adding some paste flux
      interfere with electrical qualities of the leads ?
