Keith	Re: PLate Voltage Measurements Hi Enzo - I was originally talking about a 5E3 which is cathode biased. I want to build a nice meter/tool that can measure the plate voltage, screen voltage and plate current. I did some simulations that show as long as the 6.3V heaters have a path to groung this should work. Obviously if the amp is fixed bias the cathodes are grounded so that is not a concern. I will try some measurements on my amp and put something together, no better way to find out than to try it. Keith
