TUBE REPLACEMENT
Your
Experience Elegance Integrated
amplifi er’s
conservative design maximizes life of the tubes.
You can expect that your Svetlana 6550 tubes will
last in excess of 3000, while the ECC82 drive and
ECC81 preamplifi er tubes should last approximately
4000 hrs.
Lacking the accurate time measurement, we strong-
ly recommend replacing the output tubes at 20-30
months interval (depending on your listening habits)
and signal tubes at every other power tube replace-
ment (every 24-36 months).
This will ensure that the amplifi er always performs
at its best and tube failure will not overstress other
parts.
Before you start replacement you should make cer-
tain that the unit is turned off and disconnected from
the AC outlet and that the tubes have cooled down.
Allow suffi cient time, minimum 30 minutes, for tubes
to cool down and internal capacitors to discharge.
Before inserting a new tube, inspect the tube for
cracks and physical damage.
Make sure that the pins are straight. If you need to
straighten the pins, be very careful as it may cause
the glass envelope to break, causing the tube to lose
the vacuum and fail as soon as the amplifi er is pow-
ered on, possibly damaging the amplifi er as well.
Also, make sure to inspect the tube sockets for cracks
and pin inserts. Carefully align the pins with the sock-
et and gently insert the new tube. Never force a tube
into a socket. Should you decide to buy replacement
tubes from Trafomatic Audio, rest assured that they
were fully tested before the shipment.
Only 6550 power tubes can be used.
Regarding preamplifi er tubes, the ECC82 tube cannot
be replaced with other ECC tube type (like ECC81,
83, 88), as well as the ECC81 can not be replaced
with any other ECC tube type( ECC82 , 83 , 88).
No other types of tubes can be used as they may
cause damage to the amplifi er, which is not cov-
ered by the warranty.
We do not recommend frequent changes of the
tubes, as the sockets are sensitive mechanical
parts and are rated for relatively small number of
insertions.
Servicing
Because of its careful design and high manufactur-
ing standards, your amplifi er should normally require
only minimal service to maintain its high level of per-
formance.
CAUTION
Lethal voltages are present inside the amplifi er.
Do not remove the amplifi er’s bottom cover and
do not tamper with components inside the unit
even with the power turned off. Servicing should
be left only to authorized and trained personnel.
