[Boatanchors] Need Navy "DU" Loop Antenna Docs

[Ed Sharpe]

We could  use a  manual  copy  on  du-1


Also a  set  of  cables.  
 
We are  going to  pair it  with a nice  RX in the  display!  Had  it  for   10 years atop a  shelf -   nice to have   the receiver to match it  with.
 
Thanks in advance      responses off list  to  save bandwidth  etc....   Ed#   www.smecc.org

Gang, Subject says it all.  I have the DU-1 manual, but there are some important differences.  The big one, what vacuum tube is used?  DU-1 used 2 12SK7's but this uses a single 7 big-pin with plate cap. Any help appreciated. Al -- Al Klase – N3FRQ Jersey City, NJ
