The elusive Indextron

The other relavent masking on the board reads :
1-642-164-11




The reverse of that board other components with a soldered shield, which I have not removed. So no other information can be provided about now.

This xav-u50 definitely has caps swapped out, and they are in most of the places I have visually identified leakage on the xav-55n. I will provide photos as possible, and list the masking id's of the obviously replaced caps.

So far , the only difference between the 2 is the replaced caps, an extra power harness for the xav-55n, to facilitate use without diversity unit (I assume). There is also a small board on the bottom side of assembly board "B" on the XAV-U50, which I suspect was a service update. It is secured only with double sided tape, and manually soldered in.

If any information regarding these 2 models (xav-u50, xav55n) is desired, please post. Disassembly will not liekly be performed once units are functional.
