 How much difference will 1 volt make on the filament? Mike

Can I test a 3CX1200Z7 tube in a Heathkit SB-220 amplifier? I have a
6.3
volt transformer I could use for the filament. The pin connections are
the
same. I could position a blower over the tube to supply the force
air
cooling. I have 2 tubes that are pulls from a local low power
FM
transmitter. They came from a Henry 1kw amp. I would like to check before
I
decide what to do with them. Thanks
Mike
