He had 3 of each. Which I guess he should of had 2 220 and 4 22.0k but on board 1 there is 1 220 in R1 1 22.0k in R2 and 1 22.0k on the chip. On board 2 there is 1 220 in R1 a 22.0k in R2 and a 220 on the chip.

It should be 22k on a chip, but prevoiusly you mentioned that the one with a 220ohm resistor works fine?

No the 22.0kohm one works fine the other one does not. The one with the 220ohm resistor is about 500 time louder then the one with the correct 22.0kohm resistor. I just listened to the quieter channel and it sounds like its at the right volume while the other channel I can have my source turned way down and its still very loud.

Use any 22k resistor you can find and I will send you a Caddock in a meantime.

I also planned to mention that thing. Input and output wires all twisted together don't look to hygienic to me soundwise.

Shielding the wires is not needed. Look inside that $30k preamp, twisted pairs only

let's keep the twisted pairs and add shields.
Where would you connect the shields? audio ground, input ground/return, PCB signal ground, Safety Earth?
