To prevent serious injury, electrical shock or fire:

•   Do not operate with bottom plate removed.

•   Keep away from rain and moisture.

•   Disconnect all cable connections before changing fuses and/or tubes.

•   Do not replace tubes without reading instructions.

•   Do not replace fuses or tubes if you have any doubt about your ability to 

do so. We accept no responsibility for any personal or material damage 

due to incompetent use or users.

 ca11 from its packaging. Use the white gloves.

•   Remove tube cage. Carefully pull it up and away from the preamplifier.

•   Replace cage back in its place if desired.

•   Check to see the power switch is off (down).

 preamp inverts phase. Connect positive (+) to positive and 

negative (-) to negative at your poweramp, then positive to negative, and 

negative to positive at your speaker. Do so for both speakers.

•   Plug powercords into pre- and power amplifier, then into wall sockets.

•   Switch the preamplifier on and wait for 30-60 seconds to warm up.

•   Switch the poweramplifier on after the preamplifier has been on for 30-
