Hello all,

I have a acquired a Bell & Howell 614 CBRM recording amplifier, which was built as a tube mixer/microphone amp for the JAN 16mm film projectors. I have done an exhaustive online search but can find no schematic for this unit. I believe they were also made by Viewlex (and maybe others?) to the same mil-spec. I have the military-issue operator's manual for the projector and amp, but it has no schematic. Please contact me at leoj.gills@yahoo.com if you can provide this for a fee. Thanks.
