 Electronic diagram absolutely respecting the original LA-2A version and therefore the original sound of the machine, but with a filament power supply (6.3V) and high-voltage (275V) regulated & stabilized giving the device a very good signal / noise ratio . Notched potentiometers allowing stable and precise repositioning. Active relay bypass system. Choice of Sowter or Lundhal transformer.
