TUBE ROLLING

!
The TORII JR can enjoy the benefits of tube rolling. Even though you can't roll different
types of output tubes without re-biasing, you CAN roll different types of input tubes.
!
In addition to different input tubes, you may also try different brands of 5U4 rectifiers.
(The first filter section in the power supply features a 47uf 500V cap. If using 5u4 substitutions, such as
274B, 5AR4, GZ34, etc., make sure the tube can handle 500 mili-amps or more and can handle the
inrush of the largish 47uf cap.)
!
THE BIGGEST change to how your amp sounds will likely be from the input tubes, of
which there is one for each channel. Different brands of the same tube will usually
sound different.
!
You can be assured that the stock tube compliment that shipped with your amp will be
hard to beat, as it was carefully tested in your actual amplifier and evaluated during
several listening tests!
