I looked at the table of contents and the fist few pages and the book is 100% legit, the real thing.  There is nothing unconventional in the book, it's the same material that's still being taught to this day.

Grumage is getting HF negative pulses across R5.  Go figure...

My fist thought is that is due to a bump or step in the voltage on C3 associated with the switching.  The C3 voltage is at the top of the LED array.  The bump will charge C5 with a voltage step.  Then C5 will form an RLC resonator with R5 and the interconnect wire inductance that forms the R5-C5 loop.  So it could just be normal ringing.  The ringing looks like it could be around 10 MHz.  Does that sound about right?  Picowatt would save the day.  lol

I can't really digest Grumage's nice scope shot.  I skimmed over earlier postings so I may have missed something.  Nice to see things are progressing along!
