Boss SD-1 help!

[Dave Simpson]

I was modding a brand new Boss SD-1 and the trace came off of the PCB where the R2 resistor is when I was sucking up the solder to remove the resistor. It was the top hole where R2 is located. My question is where should I jump the resistor lead to? Help!!!!!

R2 is the resistor right under "J"


On the schematic R2 is the 470K resistor

  It's put between the divider and the Q1 Base node.
  Just patching right across where the break is?...find a spot on that trace and carefully sand/remove down to clean copper and tack on a wire with solder?
  The schematic is a partial, but finding the V divider resistors shouldn't be a problem, perhaps the side of the 470k which connects to base is connected intact to the base?...then you could jumper from the other end of the 470k to the divider at 1/2v.

Here's a picture of the back side of the board and the spot where the trace came up.



Thanks petemoore I'll give your suggestion a try.

   Use the DMM to verify where you're putting the patch actually does the trick, put the patch in the..
  easiest Vs. shortest place.

Does this help?



This picture is upside down from yours, so the problem area you're working on is at the top right in the above pic.

Doing the Keeley mods?
I did them on my SD-1. Really opens it up.
