-shabtek, thanks for the tip. I'll desolder the gain/boost pot and see if its working properly.

Pulled out the pots from the LMF section, and they seem to be working fine. Any other components that need checking to get this section going?
Thanks
Craig

The schematic on this project is kind of hard to track down. See the attachment PDF.

I must chance the number, 2 friend of mine cancelled, because they are angry. Now I need only 10 but this is 100%.

Craig, did you ever figure out your LMF issue? I'm having the same thing happen.

I'm in for 2 PCBs if another run is being considered (don't suppose there's any self-etch or gerbers around is there?).

Craig nevermind I got it. Check the voltages on U4. My -V was 2 volts lower and that's what killed it. I resoldered that and it works fine! The odd thing was, that measuring the same place for continuity said the connection was ok, but power it up and I was missing 2 volts!
I got my LMF working. I pulled out the pots and resoldered all related components (again), and it finally started working.

Got a full kit including PCB's, Case and faceplace, knobs and components. Add a toroid and some connectors and you have the whole deal ready to build. Need to unload some stuff so anyone wanting to build one or get a couple more chann;es can have it cheap.

You should ask PeterC, he's the one who've launched this project and who's making boards.
