Initial Setup and Assembly
1. Never remove the bottom panel of the amplifier. There are no fuses or user serviceable
components in the amplifier, and dangerous voltages could be present if the bottom cover is
removed. Removal of this cover or any tampering with the amplifier will immediately void the
warranty.
2. Never plug the amplifier into the power source without all tubes in place and the protective
tube covers attached to the top plate of the chassis.
3. Always use a correctly grounded power outlet to ground the chassis of the amplifier. If there is
any question about this refer to your dealer/importer or a qualified electrician.
4. Never connect the amplifier to any other audio components until directed to proceed later in
this manual.
Assembling the Orfeo 60 requires that the 845
power triodes be placed in the tube sockets
prior to plugging the amplifier into the power
outlet.
NOTE: This procedure is not difficult or
dangerous if done according to the following
instructions, but it does require some care in
handling the 845 tube. If you are unsure of
yourself or would like more help than can be
given in this manual, please contact your
dealer, who will be pleased to help you set the
Orfeo 60 up. All of our dealers are chosen with
this service in mind, and we urge you to request
dealer assistance in setting up your system.
Follow these steps in inserting or changing the
845 tube. (Total time for this procedure:
approximately 15 minutes.)
1. Be certain the Orfeo 60 is not
connected to a power source. This is the
most important step! The amplifier could be
damaged if power is applied without the tubes
in place and extremely dangerous voltages are

present and assessable at the tube sockets if
power is on!
2. Remove the 845 tube from its wrapping.
It is important for tube life that oils from your
hands do not get on the upper part of the glass
tube envelope. Insert the 845 into the large
socket, taking care to line up the bayonet pin
protruding from the metal base of the tube with
the slot in the tube socket.
3. Push down on the tube until you feel that
the pin has reached the bottom of the slot in the
socket. Some force and slight movement of the
tube may be required to get the tube to clear
the contacts and go down far enough so that
the tube can rotate. Do not apply too much
rotational force until you are
