OPERATION
1. Installing the vacuum tubes
Please remove the vacuum tubes and the Vulcan from box and place the Vulcan on a firm,
level surface. Insert the vacuum tubes in accordance with the designated tube numbers into
their relative assigned sockets. Note: It is very important to insert the tubes in the correct
location. Important: Pay close attention to the direction of socket pins. If the direction is wrong
and you force the tube, damage to the socket pins will occur.
NEVER FORCE A VACUUM TUBE INTO PLACE. Tube should glide right in and have to fit tighten
(good pin contact). Ensure that all of the tubes are fully seated in their sockets.
