Tubes installation
(If not already installs)
During the transportation the tubes are kept in an appropriate box and then they must be
placed in the correct position (see the photo above).
The KT88 tube is indicated either by letter A , B ecc., which stand between the pins and
are written on the base: that is the right place for the tube to be installed.
BE CAREFUL: there is only one correct position for the tube! So please check the right position
of the eight pins and do not force the installation in any way: You could seriuosly damage the
sockets
