[Doris The Diode]

Thank you Ed.

It would better if I had letraset or the skill to do nice lettering.

I forgot to mention that I used a veroboard and have tucked away the other heater wires incase I need them for the future as I thought I would use them in this project.

For the grid pot I have used a multiturn device and this has really improved the adjustability of the grid Volts when testing something like an ecc83.
The 20V meter reads two decimal places which is nice when fine adjusting with the multiturn pot.

I've made "Valve Spec Strips" which can be put by the pin terminals, which makes the wiring easy and you can read off the parameters quickly.
