The dividers and sustain gates

The master oscillators produce square waves. These square waves are used to trigger the divider gates. The same circuit of the original E310 produce exact the same sawtooth waveform, only mirrored. The mixer in the final stage will reverse these sawtooth to the original shape.
The big difference in this new circuit is the positive power supply.
In this case PNP transistors BC557B will be used.

I have monitored these sawtooth waves and compared them with the original.
No differences here !

The sustain gates are like the original ones, only with PNP transistors.

Cheap BC557B transistors are very suitable for the dividers and sustain gates.
