[Elecraft] [POSSIBLE SPAM] Re: D-104 Mic Element Replacement

[Dr. William J. Schmidt]

No replacement available...

Well... that's not entirely True.  If you search a little, you can find
places all over the internet where you can buy "old stock" or "removed" D104
elements.  Just depends which one/ kind you want.   IN FACT just a few years
ago I bought a hand full of "authentic Astatic, old stock" the later crystal
replacements... brand-new... from one of the big electronic houses like
Mouser or Digikey (can't remember which one actually).  I think they were in
the $28 each...   

Just search.  Here are a couple that I found in 30 seconds:

Are you referring to the original non amplified D104?  If so, there is no
replacement available.  There is a lengthy thread about a proposed
(dormant) project to recreate the element here:
