Installing the valves
If your SAM-A1 amplifier did not come with the valves installed; see section 7 for instructions on
how to fit a valve to its base.
The valves will all be in boxes labelled with their position in the amplifier, valve V1, V2, V3, V4, V5
and V6.
(Each valve will also have a unique number that will be written on the box and written on the glass
between the pins at the base of the valve – just in case the valve and its box get separated/mixed
up).
Remove the valves one at a time from their box and insert them in their defined locations as per
the picture below.
If the valves are correctly installed, the base of the valve will sit flush with the top of its ceramic
socket there will be no pins (or virtually no pins) visible and the valve will be vertical – see next
picture.
