I did a thorough forum search, but I don't see any responses here. Apologies if this has been answered before.
In the output block of the W295b, there is a feedback network with a capacitor, a fixed resistor and two trimpots.
It seems the purpose of the 5k R29 is to set the overall gain of the circuit (+/- around 5dB I expect). I don't understand the purpose of R31 though. I assume this is for some kind of calibration. Can anyone explain this to me?
