Where does pin three (P1) connect. I may have trashed both units. Are
schematics available.
I don't know of any schematics. I would take it apart and see if anything is
connected to any of the other pins on those connectors. Or measure the
resistance from the outside.
I also know of no schematics, but I took some photos when I made the 10
MHz output and the
distribution amplifier for mine. The power input seems quite simple.
Everything goes straight
into the DC/DC converter. Probably the input is not referenced to
ground. There are just some
chokes and a reservoir capacitor. There is a diode, too. It looks too
weak for use as a crowbar
or as a series diode.
