It is a nice design. I like the compactness of it. I just figured out the Step Gen output and External input "trick" this past week. I wonder if the Tek engineers had this multiplier in mind when they added those jacks? It sure makes it simpler to hook up an external multiplier.
I like the one I made based upon ChuckA's design (I admit I am biased : ) ) as I can leave it hooked in and select "0" multiplication (as well as 50). Though the one I built goes to "only" -150V. I also prefer a linear power supply over a switcher and a wall wart supply.
