Roy and the group,

I agree with putting a "sand" resistor in series with the power lead to the fan.  I've done "similar" installations with other tube radios.  The slower speed does not reduce the cooling effects.  It DOES make things less noisy and reduces the vibration aspects.

Good on ya Roy!

A good suggestion for ANY old BA!
