Installation of Tubes, Tube Cover, Location and Ventilation

There are two different types of Small Signal Tubes (12AX7A and 12AT7) used in each channel. Tube type can be found on the outside of the Tube. The MC2102 will not function if they are inserted into the wrong socket.

Small Signal Tubes:

1.Locate a 12AX7A Tube.

2.On the top left side of the amplifier, locate the Tube Socket that has the nomenclature V1L 12AX7A next to it on the chassis. Refer to figure 4 and 5.

3.Orient the Tube so that the area where no pins are located on the base of the Tube is aligned with the corresponding area on the Tube Socket.

4.Carefully insert the Tube into the socket until the base of the Tube is fully seated in the Tube Socket.

5.Repeat the above steps for the remaining three 12AX7A Tubes.

6.Locate a 12AT7 Tube.

7.On the top left side of the amplifier, locate the Tube Socket that has the nomenclature V3L 12AT7A next to it on the chassis.

8.Insert the Tube, following the same procedures as in steps 3 and 4.

9.Repeat the steps 6-9 for the remaining three 12AT7 Tubes.

Caution: To prevent electrical shock make sure that the MC2102 Tube Cover is installed before connecting the AC Power Cord.

Before operating the MC2102, locate the previously re- moved Tube Cover and perform the following steps:

Installing the Tube Cover:

1.The Tube Cover has a wide opening along one side of its longer dimension. Orient this wide opening so that it is facing towards you.

2.Carefully place the Tube Cover onto the MC2102 while at the same time aligning the screws with the openings on the MC2102 Chassis. Refer to figure 6.

3.Using an appropriate screwdriver secure the Tube cover to the chassis, approximately five turns, do not over tighten the screws.

Adequate ventilation extends the trouble free life of the MC2102. The suggested minimum space for operating the MC2102 is 24 inches (60.96cm) in width, 22 inches (55.88cm) depth, and 22.5 inches (57.15cm) in height. Al- ways allow air to flow through the ventilation holes on the bottom of the amplifier and a means for the warm air to es- cape at the top, refer to figure 7. For installation of the MC2102 into a cabinet, refer to the next page.
