L-R Remote Arrows:
There are two functions that can be selected
for the Left-Right Arrow buttons as follows:
Off – the remote Left-Right arrow buttons are deactivated.
BAL – the remote Left-Right arrow buttons will control the balance.
Power-On Override:
When activated, the unit powers on when the
AC power is turned on without needing push the front panel
power button.
Reset to Default:
The amplifier controls are set to Balance = 0,
Display Timeout = Off, Home Theater Mode = None, and Display
Brightness = 8, and Remote Left-Right Arrow buttons set to Not
Active.
Tubes
The Z10e is supplied with selected vintage tubes. The tubes
operate at low current, which allows them to have an extended
life.
Changing tubes:
EL84: The power tubes are self-biasing and do not need to be
matched for gain.
12AT7: The 12AT7s should be a matched pair.
12AU7: These are used in the preamp section (the smaller circuit
board) and in the power amp section. In both cases, the 12AU7s
should be matched pairs and each individual tube should have
both of its triode sections matched as well.
The sockets are tight, so gently rock the tube pins until you are
able to remove the tubes. We use high-quality ceramic tube
sockets with gold pins which are designed in such a way that the
white ceramic part may shift slightly. This is an intentional design;
the tube socket is very secure.
