IC-R10 Discriminator

[nixbeau]

Hi guys, i need to create a discriminator on the r10. I see any text buy i dont undesrtand nothing...

the text is:

1. Install a new mono jack on the left hand board. The jack can be mounted just below the flexible/cable.
2. Mount a 47k ohm resistor on the center pin of the CI-V jack marked Q5 on the right hand board. Solder a wire off one end of that resistor to the bottom end of the 47k resistor (R77), which is located just above
and to the right of the letters QM.
3. Solder a small gauge wire (3 to 4 inches long) to test point QM. Test point QM is indicated by a line that
goes to the right of the letters QM. Then solder the other end of that wire to the TIP of the new mono jack.
4. Solder a wire from the ground lug to any point on the ground plane.

Anybody can make to me a eletrical schematic, because a dont understand nothing...

very thx...

If you haven't done this by now, this should help. I just did this to mine. And for anybody else that is wondering, well here it is.

First pic show the 47k resistor connected to the CI-V.

Next shows the whole main board and where everything goes in general.

Bottom left shows the wire from the CI-V connecting to R77 and the yellow wire connecting test point QM to the ground side of the mono jack.

Bottom right pic is another view of test point QM.
