Mesa/Boogie TransAtlantic TA-15 User Manual

PAGE 11
Now that we have reviewed the features and controls of the Front Panel and you have a handle on how they interact to achieve the
sound you want, let’s move to the Rear Panel and cover the features found there.
FUSE:
This is the A.C.’s (Alternating Current) main fuse and provides protection from outside A .C. fluctuations as well as power
tube failure damage. Should the FUSE blow, replace it with the same rating in a Slo-Blo type package. The domestic U.S. version
requires a 1.25 amp Slo-Blo FUSE. A power tube short or failure is often the cause of a blown FUSE...Follow
the cold start procedure mentioned in the ON/STANDBY switch section and watch the power tubes as you flip
the STANDBY to the ON position. If a power tube is going bad or is arcing you will see it! Flip the STANDBY
switch to Standby immediately and replace the faulty power tube and the FUSE if necessary.
If you see nothing abnormal as you switch the STANDBY on, it is possible that a power tube shorted temporarily
and blew the FUSE. If this is the case it may work again normally. To be safe, you might want to replace just the
adjacent tube or all power tubes in the “shotgun” troubleshooting tradition and save the replaced set as spares.
Spare fuses are a must for the fabled cord bag along with your spare tubes. Always carry both for they could
be worth their weight in gold someday.
A.C. RECEPTACLE:
The removable “Euro” Style” A.C. cord that is supplied with the Tr a n s aT l a n T i c makes set-ups and tear-downs
after the gig a snap. Additional heavy duty cords are available should you ever need one...simply call us and we can ship one directly
to you for a nominal charge, plus shipping cost. Make sure the A.C. cord is firmly in its socket (receptacle)
before powering up the amplifier.
NOTE: NEVER ALTER THE THREE PRONG POWER CORD IN ANY WAY.
SPEAKERS:
The TransAtlantic TA-15 provides one 8 ohm and one 4 ohm speaker output. This enables you to use many dif-
ferent combinations of speaker setups. You should experiment with different loading conditions as there may be a certain impedance
mismatch that produces a sound you may prefer to the correct load condition. This will not hurt the amplifier, however mismatching
in the higher direction will wear the power tubes faster. You will find sample speaker wiring diagrams later in
this manual and when you get time it would be a good idea to browse this section to understand more about
different ways you can use your TA-15 with alternate speaker combinations. We build many different types of
Extension Speaker Cabinets, all with unique characteristics.
That covers the features, outputs and functions of your Tr a n s aT l a n T i c Ta-15…now it’s up to your imagination as to
how best to utilize all this expressive power. If you have any questions or concerns unanswered in this guide, please
feel free to call our Customer Service department and ask for a Product Specialist who will be glad to help you get the answers you need.
Cheers and Enjoy!
