SOURCE SELECTION
!
The TORII JR. has a silver contact source selector switch for each channel. It is
located directly in-between the two input RCA input jacks on each channel. The
handle of the switch will point to the jack that is selected. Using a switch for each
channel costs more but locating them in-between the input jacks makes it possible to
replace about 14 inches of shielded cable with a single 1 inch piece of silver wire.

VOLUME CONTROLS
!
Continuing the theme of eliminating all possible internal cabling, dual volumes were
chosen and located directly in front of each channel’s input tube. This again replaces
about 12 inches of shielded cable with a single 1 inch piece of silver wire. Also, for
amplifiers that are not configured with stepped attenuators, it is possible to make
infinitely fine adjustments to channel balance which in turn makes it possible to shape
your sound-stage around the non-symmetrical properties of your listening space.

SPEAKER IMPEDANCE SWITCH
!
The TORII JR uses the new DECWARE UFO wide bandwidth output transformers that
feature a dual output impedance to accommodate different loudspeakers that fall
primarily into but not limited only to the typical 4 and 8 ohm speakers. Since
impedance is reflected from the speaker backwards through the output transformer
and ultimately to the plate of the output tube, 4 and 8 ohm taps are only actually 4 and
8 ohms when the amp is designed at the most efficient point of the tubes plate curves.
For an EL34 that is typically around 4 kOhms. The TORII JR’s UFO’s are closer to 6.6
kOhms. This has many advantages, including more realistic air and timbre in the top
end and the ability to handle deep dips in loudspeaker impedance with grace.
!
The reason we listed the speaker impedance switch as HI and LO instead of 4 and 8
ohm, is because that’s exactly what it really is. We expect you to try the switch back
and forth many many times as you get used to your new amplifier until you determine
which of the two setting serves your speakers the best.
!
Remember a typical 8 ohm speaker can have dips below 3 ohms and peaks over 100
ohms. This is the reason why it’s not black and white. Trust you ears and you can
always be sure the switch is in the right position.
