300B Tube Pin Layout
The LARGE pair of 300B tube pins should be installed toward the front of the CAD 211 FE amplifier
300B tube sockets. LOOK CAREFULLY at the tube pins to be sure that you insert them correctly. It is
possible to force the tube pins into the socket the wrong way if you are not careful! If you install the
tube wrong you will probably damage the amplifier and the tube. This damage will not be covered by
the manufacturers warranty for a new amplifier. If you have any doubts about this, have the 300B
tube installed by your dealer. If you will look carefully at the pins and install the large pins to the front
of the socket all will be fine! These 300B tube pin installation instructions are valid for the 211 FE
only.
300B Tube Socket Pin Layout in the CAD 211 FE Amp Chassis
The LARGE pair of tube pins should be installed toward the front of the CAD 211 FE amplifier tube
socket. LOOK CAREFULLY at the tube pins to be sure you insert them correctly. It is possible to force
the tube pins to plug in the wrong way in the socket! PLEASE BE CAREFUL INSTALLING THE 300B
TUBE! If you install the tube wrong it will certainly blow a fuse and it may damage the amplifier.
Correct placement is easy after looking carefully at the pin sizes and the pin socket hole sizes in the
tube socket.
