John, the 38-116 seems to be fussy about the 6A8G oscillator tube. On mine, the tube was a bit weak, and the increased current (due to lower grid voltage) pulled the screen voltage down lower as the dial was tuned lower. I have one in mine which works better than the others which I tried, but I am scouting around for a couple of NOS 6A8G tubes for it.
