Point-to-Point Wiring.
The modern understanding of this type of construction usually
refers to components mounted on boards containing turrets or eyelets
with interconnecting wires soldered by hand. After building the first
prototype at least (4) different ways, we felt this was the most advantageous
means of construction. We currently use eyelets mounted to 1/8"
thick Garolite. Wiring is accomplished with Teflon coated stranded
wire in specific colors corresponding to their various functions.
The Teflon does not melt under normal soldering temperatures and provides
superior insulation. The component board provides stability for the
components without the use of silicon or other compounds. In addition,
maintenance is a breeze with this "logical" type of construction.
Transformers.
Transformers play a key role in the tone and response of an amplifier
and we use only USA made, no-compromise premium transformers.
Chassis.
The 16 gauge stainless steel chassis is punched on a computerized
turret lathe for ultra precision. The end sections are hand welded
and ground smooth. Additionally, each chassis is vented for component
longevity.
Components.
For durability and tone we use only selected component brands and
values, all based on listening tests. Looking at the circuit area
you'll find brands like Sprague, BMI, LCR, Mallory, Auricap, Jensen
and others. All of the resistors are at least 1W, MIL SPEC metal film
type. This may surprise some proponents of the carbon composition
type but we feel the the metal films are a significant upgrade with
respect to lower noise and reliabilty. Other components include 2W
sealed potentiometers. Why, because we want our amps to be as quiet
as possible. In fact, local players who assisted in the lstening tests
at our shop were delighted with the lack of background hum, particularly
for studio and recording work.
Hardware.
All components are mounted to the chassis with stainless steel hardware
for lasting durability. For example, the transformers, capacitors
and solder lugs are secured with stainless machine screws and nylon
insert locknuts. No cheap rivets are ever
used! If you've ever tried
to drill out a rivet or two in attempting to remove a component, you'll
understand why we don't use rivets.
Cabinets.
Besides tone, our goal was to make the cabinets elegant so we've included
stitched handles, piping, chrome corners, matching acoustic grille
cloth, stainless steel hardware and our signature Burgundy covering.
Depending upon the Pennington™ model, the cabinets will either
be made of birch, pine, mahogany, or a combination of these woods.
This was based on extensive listening tests. For additional strength,
all cabinets are of finger joint construction. Finally, the rear panels
are secured with stainless steel machine screws rather than the standard
wood screws. This minimizes stripped supports, loose panels and rattles.
Covers.
To protect your investment, LeCover™
brand black padded covers are offered as an option.
Fan.
Heat does not help vacuum tubes work better or contribute to the longevity
of any amplifier. It is not necessary, but a cooling fan is recommended
as an option.
