Cooling System
This unit uses a continuous flow cooling system that is always in operation
when the power is on to the amplifier.
Output Tubes
Your unit comes from the factory set up and fully run in for 6550 type
output tubes. Optional EL-34 outputs can also be fitted to your unit. This
requires that the bias be reset to match the selected tube type. Replacement
tubes that match your output tubes are available from the factory. Look up
the number on you output tubes and ask- for the same code number. You can
generally replace on or two numerically matched tubes without re-biasing
the amplifier. A full replacement set should always be re-biased by a
qualified technician. Good quality matched output tubes will have better
output power and longer service life than a poorly matched set will have.
Service
If you have a question about the operation of your unit, or a service problem
with your unit please call us at the factory () or at technical support (847-
949-0444) and we will be happy to help you.
Your unit has a two year warranty with the exception of the tubes. The tubes
are warranted for 90 days from date of purchase.
