Hi Joe and Welcome!!
Looks like it's a 35C5. The 6AQ5 heater current is much higher than the others with these series strung set they need to be the same. If you pop a 35C5 in it you can't hurt it. The 6AQ5 will be a problem and burn out other tubes. As for the noise sounds like you need some new caps or you've got a bad IF can.
