Need a 115VAC high speed, high volume squirrel cage blower to fit into a low profile MLA2500 amplifier to cool a single 6m retrofitted 3CX800A7. Height must be 3-7/8". The current blower is quiet and slow turning, but the volume of air is lacking. Any assistance with a replacement or a source of supply would be appreciated. Thanks, Ron W2CQM/3
