Maintenance
Attention, we advise you to contact a technician if you are not experimented.
- The tubes are standard models and are available at every good retailers. They have a life expectancy from 4000 to
6000 hours for a normal usage. It is imperative to make them warm before any use to guarantee them this life
expectancy. If you have to change them, always be careful not to burn you because they can be very warm, verify that
the supply is switched off and the cable disconnected. We recommend to replace them only by lamps of the same
model. Do not hesitate to contact us for any information.
- If there is no supply anymore when you switch on the amplifier, the circuit breaker is probably activated. In that case,
check that the button GAINS is in position 0 (standby), check that the button MARCHE is off, disconnect the grip of
supply and press on the circuit breaker.
- Be sure that the speaker is connected before switching on the amp. Pay attention that the impedance is compatible
(output jack 8 ohms).
- Do not put liquid on the amp.
- Let your ampli adapt itself in case of strong temperature variation before switching on it.
- Never forget that tubes are made of glass.
