Care and Maintenance
Placement
The amplifier must be placed on a hard flat surface with plenty of unobstructed space
around the Power 1 to allow for free movement of air for proper cooling. If the amplifier
is to be placed on a carpeted floor, a Wood, Ceramic, Concrete, Marble... tile or slab
15” x 20” (or larger) must be place under the Power 1 Amplifier.
If the amplifier is left unattended or is exposed near small children or pets, it is recom-
mended that the tube cover be used. Cooling of the tubes is not as effective with the
cover on, although it does allow for adequate operating temperatures.
How do I know when to replace the tubes?
If the tubes lack power to drive your speakers, are hard to bias or won’t hold bias, it
could be time for replacements. Power tubes generally wear faster than small signal
tubes, but how much faster depends on how often you run your system. If you need help
determining these factors or sourcing replacement tubes, contact your Sonic Frontiers
dealer, Sonic Frontiers or The Parts Connection (a division of Sonic Frontiers, 1-800-769-
0747 in the U.S. or Canada, (905) 829-5858 for elsewhere) for further assistance.
Cleaning
Sonic Frontiers recommends only a dry cloth be used to clean the Power 1 Amplifier.
Sonic Frontiers does not cover warranty damage done through liquids spilled on circ u i t ry.
