That is silver tarnish, Silver Sulfide.  Contrary to popular belief silver tarnish is not conductive, it is a semi-conductor.  Short of dismantling the amplifier and cleaning the coils there's not much you can do about it.

I have a TT-425 also. Nice amp, very little drive needed for 1KW and not much more for 1.5kw.
To much dirve and pop-go the 800's 

The Silver on the coils has oxidized. My amp has some also and I will leave it as is....

Best Regards,

These could be 'medical pulls', although with the box they sound new (NoS).  You found a small fortune!

I also run a TT Titan 425 with my Flex 6600M. Great amp ! However tubes are getting hard to find and expensive. Keep the grid current low to maximize the life of the tubes. You are sitting on many life time supplies of tubes !
