Default Re: Mullard Valve Tester Card Project

HI Humphrey, in theory , yes.
In practice the holes to connect the supplies to the correct base pins is easy, as is the selection of heater voltages.
The difficult bit comes with the electrode voltages and the pass/fail limits. This is because the valve is not always tested at the voltage and current levels shown in valve data.
There may be some more theory on this in previous threads.
