Putting a feeler out to see if there is any interest in purchasing a spare blower wheel for your L-4B amplifier.? ?I have a found a source for an almost exact replacement for the cooling fan.? ?This replacement fan is the same diameter, width, number of vanes and correct rotation.? The difference is in the shaft hub diameter.? The original Drake fan fits on the 0.25 diameter fan motor.? The replacement fan hub is smaller and has to be bored out, maintaining concentricity and perpendicularity for proper airflow.
I have made ten of them and they have all been spoken for.? ?I am contemplating making more if there is interest.? ?If there is enough interest, I will make them available.? If you are interested, please contact me offline via email at
