A neat little project, & I pretty much cloned his one exactly... credit to Grant for his design at http://www.valveheaven.com.
The noval and octal sockets are wired in parallel to numbered banana leads allowing me to set up for the pinouts of different Valves. Onboard metering for Plate current and Grid Voltage.
Features:
-Shorts test
-Emission readings
-Gas test
-Gm (indirectly by readings)
-Various datasheet Plate/Screen Voltages up to 250VDC using a DC voltage multiplier and switching.
-Adjustable Grid Voltage by Pot.
I recently bought a box of old radio valves on trademe, so this will be useful to comb through when I get time. It seems there's a lot to learn about valve testing, so this will be a great learning tool. (Nice to have it off the bench, now I can resume the SR build!)
