[ARC5] "New" headphone cord set.

[DSP3]

Ken,

As someone who has been there and done (tried?) that, let me relate the 
following.  The cords within the HB-7 headband were installed before the 
outer stitching took place.  In extremely rare cases have I been able to 
replace the cord within the leather, itself.  The later HS-33's, as used 
by the USAF in the 60's, that had plastic headbands, were doable.  
However, I personally, have not seen the cord sets as a stand-alone item 
for a very long time.  I believe these were replacements for helmets or 
maybe those Navy cloth head-caps?   They are not listed as a replaceable 
part in any TM or T.O I have that talks about HS-33/HS-23 headphones and 
related interphone systems.  Most of the HB-7s I have tried to remove 
the cord has been unsuccessful as the cord had swollen or the leather 
has shrunk making it an extremely tight fit.   I was fortunate a few 
years ago to find a larder of new but stripped HB-7s at Bananofsky's 
(Barans Surplus) place.  There were, for a while, Japanese copies of the 
HB-7 around.  They are identifiable as the element retaining pins are 
larger that those actually on ANB and R-14 elements.  One has to 
slightly ream out the tiny holes on the element(s).  And... as you point 
out, working with tinsel cord is a chore.  I have been able to remove 
and clean out the end caps that mate with the elements and re-use the 
piercing feature of each on the tinsel cord ends.  There's generally 
enough service loop left to do this. Soldering is... difficult?   The 
one thing I really hate to see (but often the only remedy) is to re-wire 
with zip cord.  They work but look punky...!   At least PL-54s, et al, 
and JK-26s are still available.

All this probably won't help you one whit, but info is at least good for 
the archives...hi!!
