It looks like you should be able to but can anyone confirm if the blue, one-piece board from the store can be split into two to stack one channel on top of the other? Just in the interests of saving space and shortening signal leads
Thanks, Simon

Maybe? I’m not sure if it’s been done before, but my recollection is that there isn’t any connections between channels.
Thanks. I’ll leave it as the nuclear option, then. I got lucky soldering the SMDs the first time, I can do without the flop sweat 🙂
I asked the same some time ago, Mark Johnson answered in his unique, thoroughly way: "yes". (#1609)

I hooked up everything on the WLS project. The LED lights both come on. When I measure the voltage at CN3 and CN6 they are both 4.5 volts. When I adjust the pots nothing happens- still 4.5 volts. I didn't turn the pots all the way in and all the way out. But a turn and a half or two did nothing. Any ideas out there on trouble shooting steps. Picture in PDF file on previous post.
Yes, that is better resolution. But photos are needed of the actual setup to try to determine if the wiring is correct.
They are 25turn pots. Keep going and see if anything happens. LED on is a good sign.
And please, more photos. We cannot help you without a series of well-lit, in-focus photos. 🙂

Guess I was being too careful. I cranked on the variable resistors and was easily able to set the offset. Hooked everything up. (Aleph J and Cornwall-esque speakers. Success! Dead quiet- no hum. Compared to the B1 Korg, which I really like, the WLS seems even cleaner and more detailed but perhaps not quite as lush. What a difference in the bass. A lot more of it. Wasn't expecting that. symphonic pieces sound bigger, too.
So thanks to all for the hand holding and great help.

So I rushed my build and ended up pulling a trace off the one side of the board. The other side appears to work great. Not really excited to abandon all the parts from the one good side, has anyone cut the boards in half? I ordered a new board from the store already.
Don't know about issues like this, and out of naivity, couldn't the trace be fixed or "jumpered"?
I'd try that before a start-over...

I really boogered it, its from the one smd transistor. I am ready to start over, I was just curious if anyone had actually split the boards down the middle?
I started pulling off some of the transistors and resistors. I should have just taken a break, slowly worked at lifting the smd part off. I was disappointed but I also really enjoy the building process. This would be my 3rd preamp build, how many preamps does one person need lol

you can use tiny wire to repair that trace
after soldering , glue it in place with whatever - nail polish or something as that, checking your repair with ohmmeter, prior to gluing

Dear, MZM. With all due respect, not all DIY’ers have nail polish readily available in the workshop
