Set the 845 tube
bias to 100 mA DC Current
¼” bias plug
Insert the ¼” bias meter plug into the bias jack on the back of the amplifier chassis. Connect the bias cable red alligator clip to the positive (+) connection on your meter. Connect the bias cable black alligator clip to the negative
Note: Bias is factory preset to 100 mA. Bias should be reset when installing a new replacement 845 tube.
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.
