Warning
· There are no user-serviceable parts inside the amplifier. Do
not open the amp.
· Never use the amp in a high moisture environment or near
liquids.
· The Microtubes 200 can deliver more than 100 dB of power.
Exposure to this level of sound can damage your hearing.
Always use proper hearing protection when exposed.
· The Microtubes 200 can deliver more than 200 watts. Be sure
that your speaker cabinet is able to deliver that power.
· Do not cover the vent holes. The fan and vent holes are part of

lead to overheating and damage to the amplifier.
· Do not use an instrument cable as speaker cable. An
instrument cable is not designed to deliver the type of power
sent from the amplifier to the speaker.
