Bel Canto Design SET 40 Figure Input Tube Types and Positioning, One Channel Shown, 12AX7 ECC83

Initial Setup and Assembly

certain that the tube is down far enough. The metal tube base should protrude less than 1/4" from the top of the tube socket when the pin is at the bottom of the slot in the socket. When you are certain that the tube is in place, then rotate the tube approximately 1/8 turn in the clockwise direction.

The tube should be nearly vertical or leaning slightly. NOTE: Be certain that the bayonet pin is at the bottom of the slot before applying rotational force on the tube. The pin could be damaged if too much force is applied if it is not at the bottom of the slot. Place the tube cover ring assembly over the 845 and push it home into the three sockets for the banana type plugs on the ring assembly.

4.When the 845 tube is in place, check that the 4-12AX7 input/driver tubes are correctly seated in their sockets. These should be in place when the amplifier is received. If there are any questions at this point contact your dealer.
