Circuit diagram of the vision stages of the Murphy V410A.
Note the position of the V4 screen grid decoupling capacitor C19. Instead of going direct to chassis the capacitor is returned to the "top" of the IF transformer primary so in essence forms a capacitive bridge circuit. I kinda remember there was a similar circuit arrangement in an earlier Murphy TV, was it one of the V200 series?
