Teletype Friends,
I'm just getting around to working on a few projects.  One is a JAMES  
MILLEN 2 Inch simple rack mount  Oscilloscope #90902, circa 1948-58.   
I'm looking for an actual schematic, or manual, or someone who has  
one and can take a picture of the inside, up close, so I can compare  
mine to see if the components where replaced.  It has a 2BP1 CRT, and  
an outboard 2X2 HV Rectifier.  I looked on BAMA and found the 3 Inch  
version which employs a 3KP1 CRT.  It use the same 2X2 Rectifier, so  
the schematic may be nearly the same.  The Drawing and Schematic are  
dated 1948/49.  I found a nice picture of all 3 size Millen Oscopes   
in the ARRL Black Handbook from I believe 1958.
