6550WE used in the power supply. Proceed
according to the following instructions.
Installation
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

to ‘key’ the tube pins to the socket holes.
Retain the tube carton with other packing
materials for possible future use.
