Will see, because I will be connecting lighter note to b1, and will have one digital source only.
Thank you very much . Will test it tomorrow with jumpers.

BTW Gents, using a multimeter in this case- to check inputs for switch...
Which values or what I supposed to get ?
This is that I am still missing- how to troubleshoot assembly using multimeter
I just need to check which combination gives me positive voltage and which has no voltage across ?

Yes.

Does your meter have a beep function where it will make a tone if there is continuity? If not just use ohms and look for no or very, very little resistance as proof of continuity.

You need to start from the input pads and determine to which of the switch pads they connect.

Then once you know where the inputs connect to the center switch pad, connect the inputs you wish to use to the center pads on their respective sides.

I have continuity - will check it now.
One of my capacitors next to the power input (2 big black ones) has voltage half another one- 8 vs 16. Is this normal ?

Yes, I recall that's the way the fets bias or something like it.

If your connections are good from the input to the switch pads and then to the wiper of the pot (the center connections of the potentiometer) then you should fire it up again and see if it works!

It works
All seems to be good.
Can start with psu for b1 and lighter note...
Thank you very much
Resistor colour coding is the task, as my multimeter out of range for some of them ...

Great to hear! Congratulations!

What do you mean your meter is out of range for some? If it's not an auto-range meter it will have choices for ohm range...

Also I highly suggest buying a good auto-range meter. If you buy a good one it will last forever and be a good help on many projects, not only DIY audio! I like Fluke.

For now I have simple ebay mmeter.
Some of resistors for lighter note do not give any value, even then I switch between resistance on multimeter.
I will try again, maybe it is just me

I have question- connecting lighter note to b1 better from the source side or directly into the place of the volume pot ?
