[Collins] Need 75S-3B early schematic

[pete wokoun, sr.]

Aloha Collins Gang:

  The Battleship Missouri Amateur Radio Club (BMARC) operating as KH6BB is 
looking for a schematic for a 75S3B receiver presently undergoing 
renovation.  The schematic is probably for the initial production run and 
does not have the Service Bulletin 1 changes included.  For a quick check, 
look for 10K resistors across the capacitor trimmers C127 and C152 on the 
outputs of filters FL2 and FL3. If you have one that we could get a copy of, 
please contact me.
  The club has been donated a complete S line station in fair-poor condition 
with the exception of a 32S-3 power supply, the 516F-2.  With the help of 
some well stocked junk boxes and some elbow grease we can hopefully put this 
great station on the air soon.  If you have an extra 516F-2, all donations 
ARE tax deductable!
  We are also looking for an audio output transformer for the S-line/KWM-2 
series (collins pt no 667-0302-000), an S-line frequency tuning knob and a 
pair of 8722 tubes.
  If you can help, a big mahalo!
  BTW, we now have had website up about a week now.  Not much yet but just 
born:  www.kh6bb.org

73s, pete KH6GRT
