Default Re: Free Standardised Valves

Hi David,
The Sussex uses the same switch selector system as the AVO, but most people use a set of nine rotary switches. The pole is connected to the valve pin, and each of the contacts is connected to the relevant supply. 0 is not connected to anything. We did have trouble in the early iterations of the Sussex in that various combinations of grid stopper and/or ferrite beads were needed but that seems to have been resolved now.
