Chuff sound system, Item #711. This sound system is for the more pure at heart. It enables the basic sound system to
become more robust with the exhaust chuff and cylinder blow out. It contains four different exhaust chuff pitches to enable
use with light locomotives to those with heavy cylinders producing sounds from thunderous large cylinder locomotives to
that of small cylinders found on switcher type locomotives. This system requires optical synchronization with either item
#584 or #585 to obtain perfect exhaust with your locomotive. It does not work with track / motor voltage for an autochuff
operation as the standard sound systems do. If you want simul-chuff with the standard sound systems and require
auto-chuff, use two of the standard sound systems. What makes this unit more unique, other than superb exhaust chuff's,
is the fact that when the ball cocks are open for the cylinder blow out and the locomotive starts to move, the open ball
cocks actually play exhausting steam rather than the sound of closed ball cocks. This steam exhaust sound continues for
several chuff's or until the operating voltage gets higher for a faster moving locomotive and then they automatically close
producing a smooth transition to closed ball cock, full exhaust chuff, sounds. You can also manually close the ball cocks at
any time, thus leaving you in control as the real locomotive engineer. The board is physically the same as all of the other
DC type sound systems pictured above. For wiring diagrams, visit our web site technical downloads section. It also
requires a speaker to be used as well, if operated independently of an amplifier. See page 4 for a good selection of
speakers.
This unit can operate independently, or with another DC sound system, or with any AC sound system.
