Need info on Henry Radio 3002 filter
 

I recently picked up a Henry 2002A 2-meter amp at a swap. After a
good leaning it went from scruffy to looking almost like new. The amp
has had the Henry 3002 filter added and there is no information on
tuning it in the manual. Sooo...after many searches on Google and
finding nothing useful I'm looking fro a data sheet with instructions,
or just instructions on how to properly set it up.
