jadaro2600:
I'm looking for links to places where I can search through electrical components for the lowest cut-on voltage in a transistor.

Has there been any website created devoted to this type of searching - I'm trying to locate, in essence, a database of multiple manufacturers' information.

CompuTutor:

These might be of interest

Darlington FET comes to mind too...



jadaro2600:
Thank you, I'm looking for a transistor, NPN and PNP which have as low a voltage as possible for their cut-off, essentially, ..the point which the gate stops functioning and the transistor turns off.

I've been looking at Digikey; hopefully they'll send me a catalog.  the NTE catalog is huge, maybe I should go grab one of those, ...they actually have listings of these types of things.

jadaro2600:
The germanium style transistors are rather pricey.  ...the NTE100 and NTE101 are exactly the type of performance I'm looking for in a small signal low power transistor, but the per-piece price is around 11 dollars, US.

Jadaro:

As we have seen on the JT topic, the germanium transistors will work down to like .25 to .3 volts, maybe lower depending upon your circuit.

I have a few of these, hard to find but not all that expensive...IF you can find them.
