ramtazz said:Hi Mike... I assembled my Lola Mic Pre kit w/ the 990 opamps. The basic unit works fine except for the last 2 steps on the grayhill... they seem to be highly distorted regardless of output level on the attenuator. This is regardless of Mic or DI input.
Also the metering does not work at all... Nothing feels warm in the circuit. I have a power supply on order since I cannot test anything when its inside of my API Lunchbox thing.
Sure your not clipping the signal or your converters?
