[Boatanchors] transistor help needed

[Jim Wiley]

You may wish to consider the M3 Semiconductor Analyzer.  I purchased one 
some time back, and it is absolutely fabulous for the experimenter. All 
you have to do is hook up the transistor or diode, and it will tell you 
which lead is the collector, base, emitter, etc., whether it is a 
junction, darlington, FET, triac, unijunction, or thyristor type, the 
HFe (gain) and leakage, PNP or NPN, Silicon or Germanium, and lots 
more.  A truly amazing gadget for a reasonable price (about $72 with 
case, in kit form). I used mine to characterize literally thousands of 
junk box transistors and diodes so now I know what I have and which to 
use in a project.  When using a transistor or diode characterized by the 
M3, I have never been disappointed by how a former junk-box part worked 
in whatever I was building. 


No connection with M3 at all, other then being just a very satisfied 
customer.   BTW, this is the type of gadget that could be shared among a 
number of users in a small area, such as among your local radio club 
members.
