MD-5002 Board ,  I have schematic and schematic is posted many places on the internet .  A good detector but I read a few years ago a little unstable after running a while . 1N4733A  5.1 volt  zener diode should work fine !!
I am looking for the schematic now , I got it somewhere ?

HH.....................Eugene




Schematic of MD-5002 is here already in our "Thunting.com" Download section .  From June 2011 !!!

Hi! Are they use mini 4 pole DIN plugs for Seben coils, like the s-video cables?
I would like to use the old Seben Extreme PI bigger coil, for another VLF MD, Do you have the wiring schema?
Thankks, G
