I have a PDF version of the Amperite info on Ballasts and will email it to 
anyone who wants it.

The direct link to it is:

Note: do not be enthused if you find your favorite number in their list of 
ballast tubes still available.  Some time ago a quote from them about the 
3TF7 was in the order of $115.00 each with a minimum order of 50 or a hundred.
