Re: Leslie crossover caps.

[Jan Czaban <dk715@freenet.carleton.ca>]

I have found the Eminence 02001S driver to be a good replacement for the
JENSEN. 
It has a nice natural sound and seems to have a flat response. When fitted
to a 251
Leslie, it has two bolt holes in the exactly the correct location to allow
fitting the original
Jensen diffusers and horn support flanges. Whats more, it uses what appears
to
be a dimensionally identical double wound coil , albeit with a non-inverted
cone dome. 
Eminence supplies the coil assemlby for some $30 Canadian.
