Always use caution when changing tubes. The Power switch 

on the amplifier should be turned off and the power cable unplugged from the source. 

The tubes should be cool. Each tube is secured with a special tube retainer that keeps the tube seated 

properly and also helps to counter-act unwanted tube microphonics. A small Phillips screw-driver will be 

needed to unscrew the round tube retainer. After this retainer has been removed, rock the tube slightly and 

gently while pulling up on the tube and remove it carefully. When re-installing tubes, note that the pin positions 

are “keyed” to the socket. Make sure that you seat the tube pins properly in the socket and carefully push it 

tight into the socket. Reattach the round tube retainer. Make sure the rubber grommet inside the tube retainer 

securely holds down the tube.
