Tracing the inputs

I traced the board tonight to figure out how to connect the INA217 board.

RED - IN+
BRN - IN-
ORG - OUT
BLK/YEL - GND


The pads are named after the color of the input transformer wires.
There are some differences between the balanced and unbalanced boards. Some resistors and jumpers have to be fitted/replaced/removed. Resistors that are on the balanced board but not on the unbalanced are:

R3 - 2K2
R4 - 360R
R10 - 16K
R11 - 560R

None of which I had at home of course so no soldering tonight.

Balanced

Unbalanced
