Tips: Output Tubes
Your VAC Amplifier uses the KT88 kinkless tetrode. It is strongly recommended that replacement
tubes be purchased only from VAC. If, however, you want to customize the sound to your tastes,
be aware that as with interconnects and speaker cables, each tube manufacturer's KT88 tends to
have a distinct sound, as well as its own reliability profile.
Tips: Low Level Tubes
The Voltage Amplifier/Phase Splitter and driver tubes in the Statement is the 6SN7GT medium mu
octal twin triode. Your amplifier is fitted with the current production VAC Tested 6SN7 from China,
which we find superior to the NOS types we have tried. There are dozens of versions of this tube
available in new old stock (NOS) from a variety of sources. It would be impossible to characterize
them all.
The matches among the five 6SN7 are critical to the Statement 450's performance. Therefore we
recommend that replacement tubes be obtained in sets from VAC.
