[R-390] Collins 51J-4 Connectors

[Kurt Brandstetter]

Hello from Vienna !

My Collins 51J-4 (Ser. No. 2954) has 3 connectors on the rear panel that I
cannot find on a picture in the manual I have.

The green is named "Diode Load" , the white "AGC" . Whats the use for the
diode load and especially I would like to know if these are original (they
look original and also the printing on the backside for these 2 connectors.
They are situated on the right side of the rear panel left and right of the
ZF Out.

On the left side of the rear panel there is a (for me) unknown connector. It
is an old 75 Ohm connector which I saw in use for some video equipment years
ago at a TV station. I don't know what this connictor is used for.

Can someone of you give me some help and look for the pictures at:
http://members.chello.at/kurt.brandstetter/File/PIC1.jpg and
http://members.chello.at/kurt.brandstetter/File/PIC2.jpg and help me to
identify these connectors and give me some information if they are original

There is also a page with pictures from my 51J-4 under the link "Collins
51J-4" under receivers in the left frame of my homepage (after entering the
first page) at: http://www.swl.net/oe1002419 .

You can also reach the 51J-4 page directly via:

Thanks in advance for your help !
Kurt
