Hi,

Never found any permanent cure for the bright red start-up biz apart from tube change.

Guess someone will know where the red comes from. Thought  - Mercury-blueish, Copper-green, Red -Iron - wonder what cold cathodes are made from when coating oxides are burnt to the nub - probably wrong but keen for info - Chris
