If you had an Unicorn Account you could see a chart with the price development of this module and the average price asked for this module.
The R-53 is directly derived from the legendary TM-1 device.It uses a 12AF6/BD6 remote-cutoff pentode and a 12AV7 dual triode. Waveshaping is provided by a vacuum-tube "pulser" circuit that spits irregular pulses onto the input waveform. They synchronize erratically with the input pitch (if a waveform with sharp transitions is used). Combined with true vacuum-tube circuit distortion, this can provide a vast range of complex, aggressive distortion effects, utterly unique in the world.A basic ring-modulation function is also available in the unit--applying a carrier pitch from an external oscillator to the screen grid of the pentode, this allows making inharmonic sum-and-difference pitch sound effects, with a unique vacuum tube pentode sound.START UP IS 500 mA only run is 200 mA. System planning numbers should use PEAK not average values.
