Guys, I searched a lot for something like this and it seems nobody did this for dummies. So being one myselff I decided to post something :icon_mrgreen:
First of all you here is the theory behind this:
Here you have the pcb and layout for the circuit noted in the above link
https://mega.co.nz/#!gt5hibYI!9vbFakCUU ... rRtNXxaFEw
Download and burn. You have to hand pick a resistor that is closest to 2.2M, and with a muti turn pot, dial 2,472 (or 2,47 if your DMM goes off range)
Populate the board.
After that hook up everything as per the diagram in the first link. The board silkscreen tells you were you have to connect everything anyway :icon_biggrin:.
When your done, pinch your Germanium Tranny on the socket, paying attention to the pinout.
Set your DMM to DC Voltage in the 2v range and read the value. Write it down
Press the switch at the board. Write that down
Load that values in this spreadsheet . (idea taken from here http://www.diystompboxes.com/smfforum/i ... #msg910364)

First column first reading, 2nd column 2nd reading.
The leakage current and hfe will appear at 3rd and 4th columns respectively
Tell me if there is any error in the steps and I'll correct it.
