Spiking the Amplifier

Once you have established locations for your amplifiers, you may elect to immo- bilize them by using the four spiked “feet” included with each amplifier. These machined aluminum parts fit snugly over the heavy duty casters on the bottom of each amplifier and provide fixed, rounded points which prevent the amplifiers from rolling about on their casters. Given the weight of the amplifier, sharply pointed spikes are neither needed nor desirable.

If you elect to “spike” your amplifier, enlist the help of another person. Carefully tip the amplifier to one side, toward your assistant (who is supporting it). While the Nº33 is balanced on two feet, push a spike over each exposed caster, snugly covering the entire caster assembly. Gently lower the amplifier and repeat the process on the other side.
