Do any companies sell those blank RF probe tubes with metal tips? I
recall back in the 60s you could buy the entire probes with internal
parts as kits. They came with the same basic "shell" but had different
internal parts for different uses. The parts inside of them are basic.
Normally one diode and a resistor(s) or cap, or both.

I've found the schematics for several different probes, and I know that
some people build them in a pill bottle, or ink pen shell, or whatever,
but I'd like to find some of the REAL shells if they are sold.

Anyone know?

Thanks

The probe in the old ARRL handbooks was in the sort of shield and socket
used with 7 pin tubes. The pin connectors were removed from the socket
and a long screw was installed through the center tube of the socket.
All the RF probe parts were installed on a terminal strip which was held
to the socket by the screw which also served as the tip of the probe.
