FOREWORD Amtron was a sublabel from GBC Gian Bruto Castelfranchi company.
GBC has been created in 1958 and it is still in business and their kits were often labeled high kit or Amtroncraft.

VOICE this machine has nothing to do with a true Leslie: no devices in rotation, It is an analog emulation and sounds like a phaser with of course no doppler effect.
Spotted a main quad operational amplifier LM3401N.

SOUND there are 4 knobs functions on the panel:
1- ACCENT is the leslie depth
2- CENTER changes the phase - this function is also accessible using a pedal.
3- SPAN limits the effect on a specific bandwidth frequency range of the incoming signal
4- SPEED determinates the fequency of the rotation- speed can be also changed using a pedal
