Prepare

Before you start with your amplifier, the electron tubes have to be inserted and the tube
protection guard has to be put on before powered up. Usage of the device without the
protective guard is not permitted and is at your own risk!
Assembly

The Unity SE60 autobias circuit alternatively enables the use of the more powerful KT90,
KT100, KT120 or KT150 tube types.
Before inserting the tubes and in case of danger, you should always pull the mains plug.
Allow the device and tubes to cool down for a while if necessary before changing them.
The tubes are inserted into the respective ceramic socket with a slightly circular motion.
Note the corresponding connection notch and the guide lug of the socket.
