5.8 Service and Maintenance
You should clean the contact pins of the amplifier with a soft tissue and pure (100 %) alcohol
from time to time, especially if you have problems with the noise level.
It may be necessary after a longer time of operation to replace the contact pins. Replace gold
connectors each year or if there are problems with the contacts. Please see the Spare Parts list
under "Ordering Information".
Warning: Please be very careful when handling the amplifier, cleaning the device, or replacing
contact pins. The pins can be easily damaged. Do not damage the shafts of the pins, as they
have to be replaced by the manufacturer.
Replacing the contact pins
1. Disconnect the amplifier.
2. Open the housing and place the cover upside down on a soft and flat pad or cloth.
3. Grip the defective contact pin firmly with a pair of tweezers and carefully lift it up.
Make sure that you pull only in a vertical direction, not sideways, as this may damage
the hollow shaft of the pin in the housing.
4. Insert the new contact pin loosely into the shaft.
5. Grip the pin very firmly at its thinner part below the head, just above the thicker part,
and push it carefully into the shaft until it snaps in. Again, make sure that you push
only in a vertical direction. Do not push the pin too far into the shaft.
