[Elecraft] K3 Proset Question

[KBG Luxford]

The proset as currently supplied has the Heil electret element which:
(a) requires a source of bias via a dropping resistor (see the SSB 
manual), and,
(b) has greater output than the Heil HC-4 and HC-5 dynamic elements.

I mounted HC-4 and a HC-5 elements within an old Shure 444D stand 
(element selectable via a miniature DPDT switch mounted through the top 
of the mike head) and managed to fit a one transistor preamp in the 
base.  Circuit for preamp is on the Elecraft site.  Seems to work OK.
