[Amps] AL-1200 plate circuit conductor source/substitute?

[Brian Moran]

Hi folks! My AL-1200 converted to gs35b amp had a failure recently on 10m; I don't know the exact details since someone else was using it on 10m, but after inspection, it appears that the plate choke arced and de-spooled (THAT must have been exciting), and one of 'strap conductors' connecting the band switch to the top of the loading variable also has a section that failed (yikes). The person using it at the time (on 10m RTTY) says there were two noisy events, I would suspect the conductor to the loading variable failed first, then the plate choke. 

I'm going through the whole thing and will pay particular attention to the T/R relay, resonance of the plate choke after I rewind it, etc.  I'm planning on using #24 or #26 wire for the choke; I have neither lying around, so whichever I find first :-)

What's a good source or substitute for the flat silver-coated-copper (assumption) ribbon conductor being used for the bandswitch to loading C? I appreciate the 'fusing' quality, as the band switch appears spared.
