[Elecraft] Astatic D-104 Microphone

[John Fritze]

I am currently in the middle of converting a D-104 Eagle into a usable mic
and have had a bit of experience in the past with them.  I am trying to
recapture a bit of the nostalgia from my early ham days.  I paid too much
for it, but not only is the chrome flawless, but it came with the original
box which surprisingly is in really good condition.

Anyway what Don says is true, there were several models and until you
dismantle it you will not know what one you have.  BUT on the plus side,
when I removed the bottom plate, "looky-looky" there was a schematic
diagram pasted to the inside with the wire colors for my model listed.  My
mic had a large element (probably carbon) and an amplifier circuit with 9V
battery (still in there---yuck) in the base.  So remove the bottom, and if
there is no schematic, but your mic sounds like it is the same model I
described, let me know and I will try to send you a picture of the
schematic.

I ordered a Heil 5.1 rebuild kit from: * http://www.dxstore.com/heil_parts.html
<http://www.dxstore.com/heil_parts.html> * for $50.  I needed some small
parts for several of my older head sets like foam pads and so forth, so
perfect timing.
