red alligator clip to the positive (+) connection on your meter. Connect the bias cable black alligator clip
to the negative (-) connection on your meter. Check the 845 tube bias current reading and adjust for a
100 mA reading on the Volt Ohm Meter (VOM) or DC current meter if the reading is different than 100
mA DC current. Check and readjust to 100 mA again after the CAD 211 amplifier is warmed up for 10
minutes. Remove the ¼” plug from the bias jack and enjoy the music!

The LARGE pair of 300B tube pins should be installed toward the front of the CAD 211 AE amplifier tube
socket. 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.
