studio electronics amp price : $209.00

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!

potentiometer potential
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.
