Has anyone built this, and if so, any opinion on it ?
Go to the link below and scroll down to " A LOW COST, EASY TO BUILD DIY VALVE/TUBE TESTER". Theres a .pdf download link embedded there. It seems quite comprehensive enough to get through most noval/octal valves, but cannot test rectifier valves. (No affiliation with the owner of the design, all info is freely available as found on the web.)
