[Hallicrafters] Silver plated solid copper #14 wire

[James Liles]

Hi Bob:
Thanks for the response.  Found that the tin plated wire in final enclosures 
over time becomes unsolderable.  There is apparently an interaction between 
the tin and copper that produces a surface that will oxidize.  The process 
occurs much earlier when exposed to heat --- tin plated wire apparently has 
a shelf life.  This is why I'm looking for silver plated wire.

Case and point, we do a lot of rework in the final compartment of the 
SR-2000 and find that the tinned wire is universally unsolderable.  Have to 
sand down to bare copper and use sleeves to reconnect.  I purchased a 50' 
roll of tinned copper a couple of years ago and find that certain sections 
of it are unable to hold solder.  Also found that an attempt to solder to a 
tin plated final coil was a no-go without sanding to copper.

If anyone has another solution, I'm all ears.  Kindest regards Jim K9AXN
