Re: The "Sussex" Homebrew Valve Tester.
The current PCB (c/w daughter board) ie version 9, whats happened to the low voltage function which was available on the original.
Looks like a separate PCB will have to be made, incidentally the Heater select switch quoted in the BOM is wrong it ought to be a 1 Pole 7 Way, not a 2 Pole 6 Way
