couldnt find aything about this on this forum I apologize if its been asked already.
I built a Lola Mic pre and the Led signal meter doesn't work.. when I flip the Meter switch they ALL light up briefly and dim but do not function otherwise... Just wondering if anyone has insight or run into the same problem?
Thanks.

On the meter board:

Check if you placed the correct component. Wrong resistor, capacitor or diode is a problem.
Check for component orientation. A diode wired backwards is a problem.
Check for pads next to each other that are bridged together by a solder, but they are not supposed to be.
