HP-35 Power Supply Waveforms

In addition, if you measure the windings from point 1 to 2, 1 to 3 and 1 to 4 on the schematic picture, in that order, the DC resistance will increase linearly. It isn't clear to me from the pictures I've seen of the toroids and their windings if the interconnections between L1, L2 and L2 and L3 are separable, such that it would be possible to mix things up when placing them into a new circuit.
