When recapping if it was my radio I would replace the selenium diode. You will need to change the value of the 22 ohm resistor (R3?) to something around 50 ohms then check voltage and adjust. I have had good luck with 19T8 and 35C5 tubes in Z sets. Glad to see your set has a 12AT7  instead of 12DT8 that is the tube I have the most problems with in Z sets. Give the slide switch a good cleaning. Good Luck David
