[R-390] Front Panel Diode Load

[Flowertime01 at wmconnect.com]

I'm refurbing a basket case R-390A. Getting ready to install the front 
panel & I have one dangling shielded wire in the harness.  It's near the 
1/4 phone jack, the shield is connected to the jack's ground lug and the 
center conductor has no home.

I'm pretty sure this is the front panel diode load, but I get no 
continuity to the rear diode load connection. I don't see the front 
panel diode load in any of the doc that I have. 

Anybody know for sure?

THANKS!


-----------------
Bill the front panel phone jack is the front panel phone jack. It comes off 
the local line output through a couple resistors. The coax center conductor 
should be the tip of the phone jack while the shield is the conductors shield to 
the ring of the phone jack. Lots of the wire harness in the R390 is shielded 
wire (coax). It keeps the cross talk and coupling down as signals are routed 
around the chassis.

The diode load jacks were single pin test point jacks. The front panel was 
drilled with a 1/4" hole and the test point mounted.

Hope this helps.
