Installing the 6SN7 and 5U4G tubes:
Note: avoid oil or smudge on the tube glass, clean hands before installation.
1.
Find the correct tube for the socket. There is a label below each tube socket that
indicates a standard tube for the amplifier. For example, a 6SN7 tube should
install on the “6SN7” labeling socket. You MUST use the compatible tube or
serious damage may occur to the amplifier. See Compatible Tube section for all
the approved direct substitute tubes.
2.
Align the tube guide pin to the socket as below.
3.
Hold the tube base firmly then squeeze it into the socket slowly. Be sure to apply
force perpendicular to the tube socket, never insert the tube at an angle. Apply
slight rocking motion for harder to insert tube, never apply circular motion.
Apply pressure from top of the tube of the tube if needed.
