Looks like a Jim Williams schematic...?

It's not.
Tek Oscilloscope Probe Circuits, a booklet or PDF everyone should have:

That circuit is not in the link you posted??

Yes I may have fucked up as I did think it was from the Tek probe book. Maybe it is a JW design after all.

Close, it is from Troubleshooting Analog Circuits by Robert Pease who was the staff scientist at National Semiconductor.
IDEngineer:
Oh, I definitely know Pease. His articles were incredibly educational, just like those from Williams, though IMHO Pease could wander off onto tangents about his travels and other non-technical topics a bit too often for my tastes. I keep PDF's of articles from both on my cellphone for "casual reading" when on airplanes and such.

Active probes are easy to damage, and hard to fix.

With  50 Ohm I out scope get a Zo passive probe, eg P6156
https://w140.com/tekwiki/wiki/P6156

See the Tektronix Circuits Concept book Oscilloscope Probe Circuits Zo

Make one for free, BNC, 50 Ohm cable, 450 Ohm series R for 10x
