It is the latest advanced pi detector in the forum. The first problem is that its schematic is difficult to understand, with some rare or professional symbols on it. -

It is dated 1993, not really the 'latest' .Comment

I just redraw it. Most awkward and annoying schematic that I have ever did so far!
Few "fishy" and highly doubtfull moments in the schematic.
Not to mention some obsolete components.
And now when is drawn better and became readable; it is easy to see that it is obscure design.
Some "moves" on the schematic are weird, I assume it was design by some egocentric, a self-centered self-loving maniac!
Here it is, enjoy!
