Hello I bought the lmnc performance filter and i got a little problem my R3 resitor burned when i test its the -12v resistor just bellow the power connection. Here some pictures to illustrate I dont know if it come from the ribbon cable Or if its come from the stripboard attached to the pcb ( i check with multimeter no strip is touching an other) I saw i Forget to solder the power connector to the pcb so i found an other way to power this ( the stripboard thing) ![image](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/c/e/cefc84b1b73e3316f628b56c52d819341423aacb.jpeg) ![image](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/e/0/e049ba9844c5997c6dc196b4f5fa1034a3df251d.jpeg) i ---

Look and see if others have had the same problem. Use the Discourse search facility to find topics where the module you’re building is discussed. Inspect your work. Verify all components are correct values. Look for solder connections that are rough, irregular, skimpy, dull, or missed completely (we all do that!) and reflow them. Look for solder bridges between pads and remove them. Check your power connection. If it’s a Eurorack style power cabl… ---

Is there a general consensus about Calibration of the filter? ---

on the website Sam said that _“RV1 is a 10k trim pot, its to adjust how much resonance is available on the front knob. this is down to taste. completely 1 way is either resonance off or full resonance. just turn the resonance knob on the front right up and then twist RV1 till you have the max anmount of resonance you want”_ ---

Thanks… I’ll set a reasonable O’Clock setting similar to how I set up a Moog response
