Magnetron unity gain

[jlees1264]

Just completed a Magnetron and can not get the unity gain right. No matter what I do it's slightly boosting the signal. Everything else works flawlessly.

Try changing the value of R3 to 4K7 (instead of 47K). If that doesn't bring it down, change the Gain pot to a 50K with R3 still at 4K7.

Great minds...

You could decrease R3, try 4k7
Or decrease R14.
You can temporarily add a parallel resistor to either with some alligator clips to see what works best.

I gifted my Magnetron to my friend and he said the same. He loves the pedal but that was his only nit
