Just finished building a LOLA. Simple build and sounds great, the meter works great, but the violet LED (I believe d10?) never lights up even when I'm definitely way over 0VU/peak. Checked all the solder on the LED PCB and meter driver board, tested the diode with my DMM and got 1.76 with same polarity/placement as all the other diodes. The resistor in that slot tests good. Any ideas? Thanks!
