The latest Supratek preamps fitted with HT-Bypass have a switch on the top plate, near the back of the preamp, in-between the two transformer covers. By-pass only works when the switch is engaged and the Supratek doesn't even need to be powered on.
This most recent iteration of HT-Bypass on Supratek's is flawless. It provides ZERO gain - ZERO attenuation.
