The rectifier tube is a 5Y4G. If I continue with this set, I should get a 5X4G. I measured -17 vdc on each 6L6 grid pin 5. I also measured -17 vdc at the intersection of resistors 115 and 116. I had to replace both of those and didn't have exact values for replacement so I used a 3300 ohm resistor for the 3000 (115) and a 2200 ohm resistor for the 2000 (116). Also, both 6L6's tested on the borderline of acceptable (70% on my Jackson tester) and they both rattle. I think the 5Y4 also tested weak. I read that the 5Y4 is only for moderate dc requirements. Maybe a weak one just won't hack it with this radio.
