Default Hunts CRB C & R Analyser updated circuit diagram

The Hunts CRB Capacitance and Resistance Analyser circuit diagram shown in the Operating Manual on the web has component values written on the drawing which have scanned badly. I have also identified a few differences in the circuit when compared to production unit s/n 1670.

I've marked up the original manual circuit with the correct component values and the voltage readings taken from my unit. I have also corrected the selenium rectifier polarity and the position of the 2k2 bridge resistor and have added the cathode resistor to the Y63 magic eye.
