and have pretty much all the component values and placement but i get lost when i reach the second relay(the one towards the middle of the board with the pots).
The output seems to go nowhere when the realy is engaged to the clean gain pot.
Also there seems to be a couple of contacts for indicator LEDs and don't know about the resistors to ground next to the relays,is that part of the switching or to avoid pops ....?
Here's a schematic,I could not find the one i'm using and i only have it in hard copy,but this will do cause it shows the signal path for the switching.
