The nano chip cannot source enough current to saturate the transistor, which just gets very hot in my case. Increasing the pulse width makes things worse.

I agree.
However, I think Itsu is using some intermediate discrete transistors or a chip MOSFET driver, to drive the base of his power BJT (the KT926A).

Yes, I had assumed that Itsu had probably left his moset driver in circuit but it begs the question, how did Dally drive his transistor straight from the nano chip. This is important because to my understanding  a 'hard' switching transistor is essential for DSR operation.

Yes, it is essential but I am not sure if Dally drove his Power BJT KT926A (Q5) directly from the nanosecond monostable 74xx00 (U3).

Actually, all of the schematics I saw, had some intermediate transistors (Q3 & Q4) between the U3 and Q5 (KT926A or MOSFET).
...but then I read somewhere, that Dally was not the author of these schematic diagrams, so maybe someone else saw some small transistors (Q3 & Q4) between Dally's 74xx00 (U3) and the big KT926A (Q5), and had incorporated them in those diagrams as best as he could.

@ verpies

The attached schematic is the first schematic I saw from Dally's website to support his demo video. I also read that the subsequent schematics showing driver transistors were produced by others. I can see no driver transistors on the supporting photos of the VCO and Nano PCB's.
