This
will be a casual, conversation if you will, for this Application
Note. Warranties are fact of life necessities. Although I hope that
all of my amp run perfectly for there entire lifetime, sometimes
issues do arise where support for your amp is needed. In the Electronic
field we have a term for early failing components; it is"Infant
Mortality." I know it's a bit graphic of a term. But, let me
explain, electronic parts are built to last 40 and 50 years if installed
in properly designed circuits. Their failure rate is its highest
percentage during the first 5 or 10 hours of use, after that their
lifespan is measured in decades.
The
most important time of a handmade tube amps life is in its initial
use. Make sure that when you order an amp to be shipped
to you that you request the amp be play tested prior to packing
the amp. This procedure starts the warranty and should be noted
on the Warranty Sheet that is supplied with each new amp sold. For
claims purposes alone, I need to know if the damage came from factory
to dealer, or dealer to customer. At DR.Z amps we use original Sealed
Air foam packing system, and is the approved method of packing from
both FedEx, and UPS.
Your
dealer should be your first call, and if the amp was play tested
they can recommend initial settings, or answer any other question
you may have about the performance of your new Z-Amp. Make sure
that you check the obvious details first: if the box looks badly
damaged, has punctures in the cardboard, or if you hear broken glass
sounds emitting from the box as it's schlepped by a delivery person,
REFUSE the delivery. This will expedite the repair or replacement
of a damaged amp by weeks.
As
for initial tone settings, most of the tone stacks used in the Z-Amps
are quite unique, so standard setting as ones used on, say, Fender
style amps may not yield the full capability of the Z's. Experiment
let your ears tell you were the knob should be set, and listen for
the interaction as adjustments are made. This is where a dealer's
experienced input can help you dial in the best tone from your new
Z.
