No, they are NOT the same. 35A5 has a 35v heater and the 50A5 has a 50v heater. Other than THAT, they are the same. They probably changed or eliminated the series resistor 18, which looks like a candohm. Those resistors were known to be troublesome and may be the reason for the change. Don't try to stick a 35A5 back in there without checking that or it may be pretty short lived, along with some other tubes.
