Looks a whole lot cleaner!
I had a look at farnell for 68nF 2kV ceramic capacitors - and they are now surface mount COG dielectric! That is what 60 years does to component size.
But in polypropylene film there is a 68nF 2kV cap here

There are axial leaded versions, but all of them (along with many other electronics parts) are on stupid lead times as a result of Covid, Not a political statement or invitation to divert into a banned topic, but just a statement of fact.
