Services Offered:
>> Repairs
All work is
performed to the highest
standards. In addition to the
necessary repair, other parts
and
solder connections
are checked. Any possible faulty
connections are resoldered to
prevent potential
future problems.
All controls. jacks and other
connectors are cleaned with Caig
De-oxit cleaner.
This is the best
electronic cleaner available, it
helps to eliminate static noise
problems in controls
and connectors.
Once repairs are
completed, performance and
listened tests are done to
insure your equipment
is delivering the
sound quality the manufacturer
intended and everything is
working as it should.
>> Warranty
Repairs
If your equipment is
under the factory warranty, all
repair work is performed the
same as above,
with the exception
of cleaning, which is rarely
needed on equipment less than a
few years old.
Contact the products
manufacturer for warranty
details.
>> Vintage
Gear
Sometimes a simple
repair is all that is needed,
other times vintage and classic
equipment needs more
attention in order
to bring back the fabulous sound
it had in earlier days.
Frequently the work
needed to extract the best sound
possible is not as complicated
or expensive as you
might think.
Correctly done repairs or
restorations can increase the
value of vintage equipment
considerably.
I have done hundreds
of restorations for vintage
collectors and have acquired
much knowledge in this area.
>> Restoration
In terms of vintage
guitar amps and other vintage
gear, restoration of sound
quality is the main objective.
What this usually
entails is replacing all the
parts that tend to fail or
deteriorate over time.
On equipment over
about 25 years old, this almost
invariably involves the
replacement of the electrolytic
capacitors in the
power supply section. These are
the first to fail. When the amp
seems to have lost
its punch and/or has
a slight higher-pitched hum
(120Hz) in the background, this
indicates the capacitors
that filter out the
hum and store voltage that is
delivered to amp circuitry have
lost their ability to function
properly, the first
step is to replace them. This
type of capacitor is also found
in the pre-amp stages and
in the bias circuit
of tube amps and should be
replaced as well.
To preserve that
cherished tone in vintage guitar
amps, sometimes its is best not
to replace all of the cap-
acitors found in the
pre-amp and tone control stages,
only the ones that tend to fail
or degrade sound quality.
Replacements should
be selected that match the tonal
qualities of the originals,
brands such as Mallory,
Sprague, Xicon and
others offer capacitors that
suit this purpose. If you
desire, a vintage amp can have
its tone altered or
enhanced by using certain brands
and types of capacitors.
Most other parts in
vintage amps hold up remarkably
well, even after more than 50
years of use.
Transformers never
need to be replaced, unless they
short out. I believe that good
working transformers
should never be
replaced with so called modern
"premium" types. Part of the
magical sound of a vintage amp
can be in that crusty
old output transformer, besides
collectable vintage amps are
worth more with original
transformers. It
should be noted that replacing
parts such as capacitors which
are known to degrade over
time will often
enhance the value of a vintage
piece
substantially.
>> Modifications
Often the best
modifcations are the simplest
ones. Things like trying a
different brand of tube, or
using a higher
quality speaker can
make a significant improvement
in tone and not be very costly,
In vintage amps, certain
types and brands of
coupling capacitors can enhance
or alter tone quality to suit
your style. Feedback can be
altered or made
adjustable to provide a more
dimensional and responsive
sound. Some later model Fender
amps
can be "blackface
modified" for better dynamics
and tone. Marshalls made for the
US market with 6550 tubes can
be converted to EL34
tubes for an original British
flavor. I will not do any mods
that adversely affect the value
or
reliability of an
amp, or that cannot be easily
reversed.
