I'm stumped!

Just because the voltage is getting to the socket doesn't mean current is 
getting to the pin. Bad or corroded socket would be my first suspect.

Doing the voltage checks, the 6BA6 and the 6BE6 both show voltage on their 
filaments (between 7 & 8 VAC) but the filaments don't light up. Check the 
tubes on the checker and both show VG-EX. The 6CM8's fils light up just 
fine.

How can two "good" tubes have voltage on their respective fils and NOT light 
up when the third tube in the string does?
