Powering Multiple Units

Postby jmorri36 » Wed Jul 25, 2018 6:51 pm

Do I need to use separate power supplies when power multiple units through the 3v battery input?

I currently have six hooked up and tested. They all work great separately, but I'm not sure they're functioning properly when they have the same 3v power supply. Sometimes I'll see/hear about four tubes activate at the same time. Is that normal and to be expected? Or am I getting noise on the line from the shared power supply?
