[crackle]

I have attached the drawings I did for my Sussex Valve tester.
Feel free to use any for your own personal use. But do check the veroboard layouts against the schematic diagram as some changes were made during assembly. (I have done my best to updated the drawings but the previous statement is to help protect me in case I have made a mistake.)

The main component board contained all 3 modules, I have separated them just for clarity.

The relay board was assembled on a separate veroboard.

Where high voltages were involved I removed alternate copper strips off.
(Heated along copper strip with soldering iron then pulled up one corner and pulled)
