Robert discusses the construction and subsequent modifications he has done to his DIY Audio kit of the Nelson Pass Korg NuTube B1 preamplifier. Later he demonstrates how adjusting the bias of the NuTube affects the sound character of the unit. The sound is at a lower level as my sound recorder refused to work. Please turn the volume up after the intro music.
