Installation
The KT150 power tubes have been carefully matched at the factory and the tube bias has
been set accordantly.
To prevent the output tubes from damage and disconnecting, the power tubes are not
installed during transport.
The box of each KT150 tube is marked with the number corresponding to its correct location
on the amplifiers main circuit board.
Each tube should be placed in the appropriate socket before use as shown on the drawing
below.
Be careful that the KT150 tube pin alignment tap meets the matching groove on the tube
socket before pressing the tube down the socket.
Tube positioning
Input / Outputs
Apart from the headphones, all connections are on the back panel of the amplifier.
Use shielded cables to connect the signal source to the amplifier input. To minimise the
possibility of hum, the shielded cables should run parallel to each other or loosely twisted
together. Locate the cables away from speaker leads and AC power cords.
AC Power
The amplifier AC power cord is plugged into an 115V/120V/230V/240Volt 50/60 Hz wall
outlet. The right voltage is indicated on the back panel beside to the AC power inlet.
! Check that your supply voltage is the same as indicated.
