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.
It is very important to insert the tubes in the correct location.
Pay close attention to the direction of socket pins and their different diameter (AA62B) of pins.
The 5U4G and 6SJ7 tubes and their socket have a “nose” too. If the direction is wrong and you
force the tube, damage to the socket pins will occur. Never force a vacuum tube into place and
also avoid “left-right” tilting, pins can break easily. 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.
Note: When inserting and removing tubes, handle them by their bases, not by their glass bulbs.
A slight violet glow in the tube is not cause for concern.
