Please forgive this comment about my own product, but the message above 
could leave an incorrect impression.

An 'instant-on' tube doesn't need the warm-up timer on my board, but it 
does benefit from all the other metering and protection features.

The manual actually deals with this point: for 'instant-on' tubes, the 
warm-up delay can be eliminated by changing two components.
