This is a Core triangle VCO with a classical OTA controlled by an exponential pair of matched PNP transistor. A particular SAW is built from the triangle, this saw can be modulated from saw to double frequency saw to opposite phase Saw. Have a look to the video.

He has the classical trimmer for V/oct; frequency, HF trimmer plus one to set the SAW.

This VCO has is own power supply to get a very accurate tracking and frequency range.
