This thing is definitely a twisted and demented sound shaper. The name TUMOR REFILLED HALO is an anagram of the original's HellFire Modulator. The unit has 5 tubes consisting of a rectifier for DC voltage, a VCA distortion tube, an LFO oscillator tube and two tubes for adding more artifacts to the sound. The chassis is an old bench test unit that I salvaged. Eric's power circuit design uses dual transformers to economically generate the proper voltages for the the tubes at 6VAC and 140VDC and is very innovative. The overall sound is similar to the TM-1 Waveshaper . I'll send sound samples later. I'm sure the Noisefest crowd will get a rise out of this."
