This video shows the voltage input and the amps in both digital and analogue meters. One part of the pulse circuit was switched off (left in the D14 with the switch on pin 3) and you can see that the current draw is over four fold.

(For the circuit use the pg.25 schematic but with individual ferrite core rods straight wound for the Inductors rather than a single rod and bifilar wound--not recommended)
