[Elecraft] OT: Older Heil earpiece elements

[Joe Subich, W4TV]

The original ProSet elements had an impedance of 400 Ohms 
(I have a pair of the transducers in my junk box).  The 
replacement elements are 200 Ohms (I opened the ProSet to 
confirm).  

The replacement was not free but the "ProSet Speaker" is 
$4 each from Heil (check the Parts page at www.heilsound.com).
