Hi, It should be a dark green 150R Resistor across the base of the tube
Just take bottom cover off and you'll see it--replace and test--though it sounds like a dicky tube, but I have replaced them and the units operate OK.
So give it ago it is easy to resolder plenty of empty real estate in their!
God Luck,
