Measuring Hfe without a DMM that measures Hfe

[deschete]

Is there a way to determine the Hfe of a transisitor without having a DMM that tests for this?  Can I get it mathematically by measuring the voltage at the Collector and Base?

I've been looking all day for the answer but I can't seem to find it clear enough to fit into my skull.

I believe so yes, hopefully I'll have an idea in ten minutes or so.

The reason I think it is possible is because when measuring gain on GE's you use voltages.

Maybe you could come up with a way,

Over at geo theres an article tech of the ff, read that, its got the GE measuring method in it.

The same method works for germanium and silicon.

You put a know current into the base, measure the collector current, and divide the two. With silicon you don't have to subtract out the "leakage gain".

Sorry, forgot to get you an answer in 10 minuted 

My answer is, do what RG says

I have seen that formula... but the question I have is, how do I calculate Amps if I'm measuring Volts?
