GETTING STARTED
ABOUT YOUR LINE PREAMPLIFIER
Your TARA 30A Line Level Preamplier was designed to provide high value based on
itsexceptionalperformance,whichisaresultofacarefullydesignedcircuitandoptimized
componentselection.Thedesignutilizesminimumnumberofactivepartsandtopquality
passiveelements.TheTARA30wasconceivedasapreamplierwithrecognizedTrafomatic
Audio’s uncompromised sound quality.
The design is based on an excellent EML 30A vacuum tube. The EML30A is driven by the
6N30P tube, with resulting total gain of 21dB; alternatively, the 6N6P tube can be used and

designed output transformers. A dedicated dual power supply is housed in a separate chas-
sis, for maximum separation.

HANDLING AND REPLACING VACUUM TUBES
Many people have never had experience handling vacuum tubes. Process is very similar to
handling incandescent light bulbs. As with the light bulbs, you should not touch a vacuum
tubewhenitisoperatingsinceyoucanburnyourself.Similarly,ifatubeisdroppedona

allowsufcienttime,minimum30minutes,fortubestocooldownandinternalcapacitorsto

Before you insert a tube you should make certain that the unit is turned off and disconnect-
ed from the AC outlet. 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
envelopetobreak,causingthetubetolosethevacuumandfailassoonasthepreamplier
is powered on. Carefully align the pins with the socket and gently insert the tube.
Never force a tube into a socket.
The TARA 30A preamplier is designed around the EML 30A and 6N30P vacuum tubes.
Whenthetubes aredueforreplacement,please contactTrafomaticAudioorauthorized
dealer for recommendations about substitutes. The 6N30P tube can be replaced with the
6N6Pifmoregainisrequired(25dBvs.21dB).

and, if that is the case, placing this switch in the 180° position will correct the phase reversal. Also, the 180° position
can be very helpful in setups with challenging room acoustics or during integration with subwoofers.
