Re: [Amps] 3-500z - intermittent filament

There are some higher temperature 'soft solders' around, which don't require 
the red heat of hard solder. From memory, something called 'comsomal' or 
similar is about a 300 degree C or so solder. Personally, I much prefer to add 
cooling air, and use ordinary solder with a heat sink to keep the seals cool.
