SERVICE AND CARE
TUBE REPLACEMENT
If it becomes necessary to replace the tubes, the same brand as installed new should be used. A
complete new tube kit is available from Cary Audio. Although useful tube life varies depending on
the nature and degree of use, under normal home use, the 845 or the 211 output tube and the
300B driver tube should last many years in the CAD-805AE. The 6SN7 input tubes should last
even longer.
NOTE
• Any current production or New Old Stock (NOS) types of 211, 845, 6SN7 or
300B tubes will work fine in the CAD-805AE amplifier. The voltages are fine
for all available types.
WARNING
• Make sure the amplifier is unplugged 30 minutes from the AC mains before
replacing the tubes to avoid risk of shock and high heat from the 211 or 845
tube.
