Tube Replacement
The tube used in the M9 has been hand selected for low noise, and burned in to provide years of service. The tube used in the M9 is a 12AX7 type. The actual number that appears on the tube in your microphone may be different. This tube is a very popular type used in a variety music and recording related products. However, to insure continued operation within factory specs, it is recommended that you purchase replacement tubes from CAD. Contact the CAD Customer Service Department at 1-888-702-7075. To gain access to the tube, first disconnect the microphone from its power supply. Remove the microphone from the mount by unscrewing the large knob at the bottom of the mic. Remove the mic housing by unscrewing the four screws on the back of the mic. Carefully remove the housing.
