INPUT TUBE INFORMATION
The CSP2 is designed to use your choice of
three different input (or signal) tubes.
6N1P
6DJ8 (a popular low noise tube both available
in current production by numerous manufactur-
ers 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 CSP2 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.
