Some Henrys have the filaments in series, but if one tube is not lit, 
that isn't the case with yours! Anyway, you can pull out the dead one 
and it should more or less behave in exactly the same way as it is now, 
except the plate tuning will be off a little due to the reduction in 
output capacity with only one tube.
