CHANGING TUBES:
Always use caution when changing tubes. The power switch on the ampli er should be turned off and the power cable
unplugged from the source.
CHANGING POWER TUBES - The tubes should be cool. When changing the power amp tubes push down on the silver
tube retainer and carefully work the tubes out of the ceramic socket by pulling up while rocking the tube slightly and
gently. When re-installing power tubes note that both the tube base and the pin positions, are keyed to the socket. Make
sure that you seat the tube base properly in the socket and carefully push it tight into the socket. Con rm that the BIAS
SWITCH is in the correct position for the type of power tubes being used.
CHANGING PREAMP TUBES - The tubes should be cool. Each preamp 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 preamp 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 preamp tube.
OUTPUT TUBE BIAS The output tube bias does not need to be adjusted if the tubes are replaced with Ruby Tubes
EL 34 BSTR tubes that have the same PC number as the ones installed from the factory. However, if you are
replacing the tubes with anything other than Ruby Tubes EL 34BSTRs with the same PC number, then your amp
should be rebiased by a quali ed technician who is familiar with high voltage tube power amp servicing. This will ensure
optimum performance, tone and tube longevity.
NOTE: Dangerous and/or lethal high voltages are present inside the ampli er chassis. Refer all servicing to
quali ed service persons.
