Unpacking
Each Phono 1 has been transported to you in its custom travel case which has been
specially designed to protect the units during transit anywhere in the world. Given
the substantial weight and size of the phono stage, it is suggested that careful atten-
tion be given to the following:
Travel Case Lifting Caution!
The phono stage including carrying case has a combined weight of 102.5 lb/46.5 kg.
Travel Case Opening
The travel cases have been custom designed to provide the utmost in protection dur-
ing transit and storage of the phono stage. An empty case weighs approximately 44
lb/20 Kg. When not in use they should be stored away in a safe and dry location.
The weight of the Tenor Phono 1 is not evenly distributed about the centre axis from
front to back which creates a very awkward load, therefore careful attention is re-
quired!
Caution should be used in lifting the phono stage out of the lower portion of the travel
case to make sure that nothing scratches the beautiful Tenor wood and metal finish.
Position the travel case close to the final location by rolling on the travel case wheels.
Clear the space of the final location in advance and have two reasonably strong people
lift the phono stage upwards out of the travel case until the phono stage is clear of the
travel case sides. Special care is needed when installing in a shelving unit due to re-
strictive access. When sliding the Tenor Phono 1 on a shelf, do not drag on rubber feet
but lift enough weight so that rubber feet do not bind when sliding.
List of Items Included with Tenor Phono 1
•1 Owner’s Manual
•1 Protective Cover
•1 Kubala-Sosna Emotion Power Cord with country specific AC mains plug
•Package of User Accessible Fuses
Moving Your Phono Stage
Once the Phono 1 has been turned off using the top right button in the display,
turn the power off at the rear and let sit for about 10 minutes - to dissipate high volt-
ages. Disconnect all cables and power cords then put them underneath the phono
stage in the travel case with connector ends wrapped in a protective material so they
do not come in direct contact with the wood or metal finish which can be scratched or
marred if care is not taken.
Consult Owner’s Manual for reconnecting cables and power cords following a move to
ensure nothing is taken for granted. To protect the beautiful metal and woodwork, it
is always recommended to use the protective cover and travel case when moving the
Tenor Phono 1. The weight of the Phono 1 is not distributed evenly about the centre
axis making for a difficult load. It is recommended to have two people to move the
Phono 1 safely.
