HazLabs vs LHZ

This month I’ve received an authentic HazLabs preamp and a KHaz preamp to used for circuit tracing to compare to the currently-shipping LHZ-01 and LHZ-02 bass preamps.

I’m happy to report that the LHZ is a component-level match to the original Hazlabs preamp, with the only exception being that we use 100uF for the main power capacitor whereas the Haz uses a 33uF cap. (The power capacitor does not impact the audio circuitry: it is strictly to ensure steady 9-volt power in the event of fluctuations.)
