Quoting Carl <km1h@jeremy.mv.com>:

Dont overlook a good muffin fan either. The EBM Papst 4600N was used in later production LK-800's using the 3 3CPX800A7's at about 3100V. That is a lot of fin area and back pressure.

I ran a quad of 4cx250b s using a pair of stacked muffins for the extra back pressure. fairly quiet and compact.
