Vic,
Having blown up my share of probe diodes, I find it useful to stick a label
on any such homemade probe noting its maximum safe peak working voltage
derived from the diode's PIV rating.

1N91 is germanium, like the 1N34.
But while 1N34 is a small-signal diode, 1N91 is a power rectifier. That
means a lot more capacitance and back leakage. I don't know if that will
matter.
I found a 1N45. That is pretty similar to a 1N34, so I'll use it. The
drop is about 0.28V.
