Re: The "Sussex" Homebrew Valve Tester.
Hi
I have come across an issue with the first stage of the "commissioning tests".
I have built my tester with a patch bay rather than a multi way switch for each pin.
So on my tester when I check resistance between the cathode and all other electrodes there is a permanent 21k connection between the cathode and the screen grid, through R23 R24 & R33. Do you see this in itself being a problem.
I have drawings of my veroboard layouts which I can supply.
I will post some photos of the work so far.
Thanks
Mike
