Default Re: The "Sussex" Homebrew Valve Tester.

Best of luck. It’s an excellent valve tester but I would recommend that most leads are fitted with ferrite beads to avoid any possibility of oscillation. It’s easy to get and difficult to eradicate. I built mine with plenty of beads and never had any problems. Make sure that all the meters are fed from separate power supplies.
