Yeah, who/what can be trusted at all anymore? I put my sine
generator to the cap marked 220 thru a 10K [5%] resistor, and
adjusted freq until the voltage across the cap dropped to 50%
on the scope. Using Xc = 1/(2*pi*F*C) gave me a value of 130 pf
--> :). I was hoping for something ~250 = 220+scopeprobe_cap.

I then took another cap marked 270+/-10% and did the same. This
time I got a value of 160pF --> :):).
