Hi folks,
I've an EICO 950B capacitance tester with me. It has an aging 1629 magic eye tube. I have a bunch of 6E5S tube with me. Can you guys guide me with the modification?
I know the first step to this is to reduce the filament voltage to 6.3V for the 6E5S. But something that bugs me is, can a simple resistor voltage drop get it done? I'm worried that this path might have issue which might kill the tubes very fast. Hoping to get some expert opinions here.
Also I've heard the 6X5 tube have the habit of killing the transformer as they die? I'm thinking of changing it to something like a selenium or silicon rectifier?
Thanks.
