Hi Michael,
Here is a pic of my CCW Experimenters amp. I'd say this vent hole is
about the size of the center pin hole in BNC Female connector. Very
close in diameter.
Regards,
Simon

Thanks, Tom!
I wondered whether too small a hole would allow
a droplet to block the hole and defeat its purpose :-)
Simon, is your hole similar?

downward. Some of my units have been outside for 3 years now without a
trace of water inside. Tom
