from designer tim caswell’s own hand:
the amplifier (amp) is a 2 stage class a discrete design using 3 pairs of hand matched transistors. envelope is usually applied to st1/1. st1/2 goes thru an attenuverter and can be used for envelope or
modulation. st2/1 goes to the 2nd stage, and is typically used for volume control. st2/2 goes thru an attenuverter and is typically used for modulation.
the amp, the 5089, and the 3003 are class a circuits. they draw more current from the +12 rail than from the -12 volt rail. if the system power supply is under-sized, hum or buzz may be heard. in that case,
larger filter capacitors and/or a larger power transformer will be needed. the 4075 draws equally from both rails, and is more immune to hum. like our filters boomstar modular amps are hand-built entirely in the
u. s. of a—just ask rachael herbison!
four attenuation pots control the input, stage 1/2, stage 2/2, and output, delivering smooth, detailed, and complex expression.
switch it up
uber useful continuous hypnotic drone for endless sustain/release and drive—the overdrive circuit from the boomstar desktop—for last stage energy, and bite.
patch it up
six patch points: input, st 1/1, st 1/2, st 2/1, st 2/2, output direct the deepest manipulation.
all controls and patch points
input – adjusts the audio input.
stage 1/2 – adjusts stage 1/2.
stage 2/2 – adjusts stage 2/2.
drone – sustains the last note received—“hold that train.”
drive – final output stage overdirve/saturation.
output – adjusts the audio output.
input – audio input.
st 1/1 – stage 1/1 input.
st 1/2 – stage 1/2 input.
st 2/1 – stage 2/1 input.
st 2/2 – stage 2/2 input.
output – audio output.
