INPUT TUBE INFORMATION
The SE84C is designed to use your choice of
three different input (
or signal
) tubes.
6N1P (
a Russian tube from the same factory
that makes the SV83 and 6P15P-EV
)
6DJ8 (
a popular low noise tube both available in
current production by numerous manufacturers
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.
)
RECTIFIER TUBE INFORMATION
The SE84C is designed around the 5Y3GT 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.
◊
5U4
◊
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.
The sound is typically warm with good balance.
The sound is more airy and detailed, less bass.
The sound is typically more dynamic and detailed.

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
SE84C.
