Thank you for purchasing the finest tube amplifier in the business. We appreciate your support and
look forward to providing you with years of trouble free service. Before we get into the features of your
amplifier, we would like to note that tube amplifiers require a little bit of care and maintenance that we
would like to share with you. When you first turn on your amplifier remember to leave it on rest for
at least 30 seconds before turning it to go. This will give the tubes plenty of time to warm up and will
extend tube life. The chassis is built out of aluminum which is a conductor of heat. It may feel warm to
the touch, but no need to worry.
Check to make sure that the impedance switch is set to the correct ohmage for your cabinet. Improper
loading may cause excess tube and transformer wear and eventual failure. Use high quality speaker and guitar
cables to ensure maximum performance. For tube related problems, we’ve included a trouble shooting
section on page three off your manual.
