ALPHA 9500 Interim OPERATING MANUAL

CAUTION:
PROCEED SLOWLY to avoid bumping and damaging adjacent wires,
connectors or components.
While the top cover is removed, make sure the tube is firmly seated in its socket, rubber exhaust
chimney is fully and correctly installed, and anode connector is tightly clamped to the tube. The
silicone rubber chimney installed on the 8877 tube is a critical part of the cooling system. Make
sure the chimney is straight and fully installed so the bottom of the chimney is firmly against the
tube deck and completely covers the airflow opening in the deck. Tube cooling exhaust must
exit only through the tube anode fins; it must not be allowed to escape outside them. Failure to
ensure proper cooling airflow may result in tube damage or destruction, which is not covered
under warranty.
