Input Tube Information; Rectifier Tube Information; Where Everything Goes - Decware SE84ZS Owner's Manual

INPUT TUBE INFORMATION

The SE84ZS is designed to use your choice of
three different input (or signal) tubes.
6N1P (a Russian tube from the same factory
The sound is typically warm with good balance.
that makes the SV83 and 6P15P-EV)
6DJ8 (a popular low noise tube both available in
current production by numerous manufacturers
The sound is more airy and detailed, less bass.
and in N.O.S.)
6922 (a popular variant of the 6DJ8 also avail-
able by a wide variety of manufacturers and in
N.O.S.)
The sound is typically more dynamic and detailed.

RECTIFIER TUBE INFORMATION

The SE84ZS is designed around the 5U4 recti-
fier tube. It is however, compatible with the
following alternatives - each having a subtle ef-
fect on the overall sound characteristics of the
amp.
◊
5Y3GT
◊
5AR4
◊
GZ34
◊
274B
The different ratings and efficiencies of these
rectifiers will effect the operating voltage points
throughout the amplifier which is why they can
have an effect on the sound. You will find that
even different brands of the same tube will
sound different. This is true with any vacuum
tube.

WHERE EVERYTHING GOES

Below are the tube locations, input jack con-
figuration and power switch location.
The input switch, one for each channel,
changes between direct and variable inputs.
It always points to the active jack. For ex-
ample on the left side of the amp, moving
the input switch to the right would select the
variable input for that channel. Variable in-
put means the signal goes through the vol-
ume control located at the front of the
SE84ZS.
