Tube Replacement –
Tube life varies
greatly depending upon use, vibration, and
tube quality. It is uncommon for a tube to
last less than a year in our circuits. Tube life
of several years is not at all uncommon.
Symptoms of tube failure include signal loss,
distortion, and increased noise. The tube is
easily replaced by removing the unit’s cover.
Always disconnect the power cord from
the back of the unit prior to removing the
cover. Gently remove the tube and replace
with a genuine Eden 7025 / 12AX7 or
equivalent tube.
Service –
In the event of amplifier
malfunction, or questions about your unit’s
operating features, you should contact your
Dealer, the factory or one of our authorized
