Philco 640 Electrolytic Voltage Ratings?
#7

Greg

Jeff had not realized there is high voltage there at all, he thought the voltage there is 5V of the filment voltage.
This is the exercise I wanted him to do first. Once he knows it is not 5V but more like 400V, then we can explain why this 400V temporarily makes an excursion into 500V or so realm.
