Installation
Before operating the LS28SE
Your LS28SE preamplifier is shipped
with the vacuum tubes packed in a
separate foam-lined carton. These must
be unpacked and installed before you
attempt to operate the preamplifier.
Included are four 6H30
tubes for the analog stage. Proceed
according to the following instructions.
Remove all screws fastening the top
cover. Carefully remove each vacuum
tube from its protective foam and match
its location ‘V’ number (written on the
base of the tube) to the ‘V’ number
printed next to each socket. Firmly seat
each tube in its matching socket, taking
care to ‘key’ the tube pins to the socket
holes. Retain the tube carton with other
packing materials for possible future use.
Refasten top cover on the preamplifier.
