Source text from Ken Stone’s CGS website
”The Peak (Hills) module is effectively a diode OR gate. An emitter follower (the lower transistor) is used to cancel out the voltage drop of the input diodes. The upper transistor is a constant current sink acting as a pull-up.
The Trough (Valleys) module is the reverse of the Peak, based around a diode AND gate, again with an emitter follower (upper transistor) compensating for the voltage drop across the input diodes, and a current source acting as a pull-down.”
An error was found on the current pcb on the Hills/Valleys circuit. R5 connects to the nodes between pin 2 of Q2 and Ground. The Ground side of R5 should actually connect to V-.
