Diagram 1:
Inspect the locating pin on the bottom center of the valve and align with the valve base
(the locating pin can only go in one way round due to a locating spigot) and with gentle
but firm pressure insert the valve.
Looking from the front of the amplifier, the next valve to install is the 300B valve which
is inserted into the 4 pin valve base in the middle of the amplifier.
It is absolutely vital that this valve is fitted correctly
(1) The larger pins must face the front of the amplifier when fitted to their valve base.
(2) The sticker on the valves base must also line up with the sticker on the copper top
plate, that is, A to A, B to B etc., or 1 to 1, 2 to 2 and so on.
Please make sure that both (1) and (2) are correct and with gentle but firm pressure insert
the valves into their sockets.
Check again that all valves are fully inserted in the correct way in their respective valve
sockets.
Follow the above installation for both amplifiers.

Installation

Select a suitable location for the units ensuring that adequate ventilation clearance is
provided allowing at least 30cm. of space above the units. This is an important
consideration as the amplifier generates substantial heat during normal operation. Be sure
not to install the amplifier into a cabinet with restricted air flow or onto a thick pile
carpet.
