CAUTION!!!
The instrument rack (for TT-3/6/8)
must not block air passages located on the unit’s
front and
rear panels. Fans in the lower center of the rear panel pull in air for the power tube and fans
in the upper corners extract air from the unit. Allow for ample clearance for adequate air flow.
The rear of the instrument rack in the area of the HVPS MUST NOT be closed in order not to
obstruct air flow to/from the fans.
The HVPS cabinet (TT-10/15/20) must be placed in such a way that neither the air intake at
the front panel, nor the air intakes and exhausts by the fans on the rear panel are obstructed.
Ample clearance (at least 20 inches or 500mm) must be kept from both front and rear panel.
Power Tube Installation
The TT-3 and TT-6 are equipped with an indirectly heated oxide cathode power tetrode that
can be left in the power supply during shipping.
