SAFETY PRECAUTIONS:
• Read these instructions.
• Keep these instructions.
• Heed all warnings.
• Follow all instructions.
• Caution: When using the Internal Load with high output amplifiers (100+ watts), do not set the amplifier's Output (Master) all the way up.
This can stress the amp and prematurely wear the output tubes, the same as if it were connected to a speaker. If the
chassis gets hot to the touch, back down the Master Volume. Your amp will thank you.
• Do not use this apparatus near water.
• Clean only with dry cloth.

Thank you for choosing the POWERHOUSE
same strict code of fine instrument building that all MESA/Boogie Products share and we hope you find years of inspiration and enjoyment through
its features.
OVERVIEW
Every experienced player knows there's nothing like a great tube amp running in the power band for tone, feel and excitement. Be it a 30-watt Combo running
6V6 or EL84s, or a full-blown 100-watt Head cranking with 6L6 or EL34s, nothing compares to the dynamics, expressiveness, fullness and dimensionality of a tube
power amp operating in "the zone".
However, these days venue volumes are down and neighbors everywhere aren't as tolerant as they once were. That's no reason to compromise your sound and
run your favorite amp, be it combo or head, in its less dynamic idle zone ...because we've got you covered with our POWERHOUSE
