[Boatanchors] R-13B

[telegrapher at att.net]

This is part of the ARC Type 12 gear and one of the receivers that is 
similar to it is the R-19 which covers the same frequency range.  The 
R-19 can be either 14 or 24V.  You need to place a jumper across two of 
the pins on the front 6 pin connector.  That jumpers the B+ around the 
TR function that's done externally.  Otherwise, 24V fil, Gnd and B+ of 
200V or so on the back connector will make it work.  These assignemnts 
are for J303.  Pin D is LV+, C = Gnd, F= vacant, E to A is where the B+ 
should be jumpered and B is audio.

J-302 is where the control head would connect to.

Pin A is audio to a headset
Pin B is the AF cathode for loudness control
Pin C is Gnd
Pin D is is LV to pin D on J-303
Pin E is for the sensitivity control
Pin F is from the LV source and would go through an on off switch 
connecting to Pin D.

Pin F is the center pin and pin C is directly below.

This should be enuff info to get you going.

I don't have the means to scan anything for you but i could get a copy 
made for the R-19 if your interested or any other of the 
receiver/transmitter/control heads etc.

Hope this helps Dave.
