ROGERS PA-1A Phono Preamplifier

Excellent condition, original packaging.

Dual mono, class-A, all-tube design phono
preamplifier. Hand made in the USA.

In short, if you don’t need more than one
MC phono input, your search ends here. It’s that good -Jeff Dorgay, ToneAudio

Analog performance to ultimate perfection
has always been the standard at Rogers High Fidelity. Our newest performer, the
PA-1A Phono Preamplifier follows our heritage in every detail. You have not
heard your record collection until you have heard it being played through the
Rogers High Fidelity PA-1A Phono Preamplifier. It’s dual-mono, Class-A,
all-tube design has an industry leading signal-to-noise ratio and represents an
all out assault on the state-of-the-art. Unless you are listening to your vinyl
collection through our high performance, vacuum-tube preamp, you are missing
out on half of the tonal qualities that you love about analog reproduction.

 

FEATURES:

 

Made In The USA- Hand built to the most
exacting specifications in our New York Facility. All amplifiers are fully
evaluated and acceptance tested using the the best audio test equipment made by
Audio Precision. We perform all of the tests in a typical Stereophile test
evaluation and many more to characterize each amplifier. Each amplifier is
shipped with a fully evaluated test data package so that the customer can see
how his particular unit performed after acceptance.

Transferable Lifetime Limited Warranty- Our
Products are guaranteed FOR LIFE.

Parts-27 midCompletely Hand Wired- The
entire amplifier is wired by hand using all American labor in NY. The wiring is
all discrete components and all point to point. This provides a lifetime of
serviceability and reliability. All of the wiring and soldering meets the
Military Standard 2000 requirements. All operators are trained to this standard.

Aerospace Specifications- All of our
resistors, capacitors, transformers and inductive components meet or exceed the
applicable military quality standards for parts selection. We use the same
parts used by NASA in the Shuttle and Space Station equipment.

Class A Design- All amplifiers are a full
Class A design yielding the ultimate accuracy in music reproduction.

Input Stage Design- The input design uses
an ultra low noise tube design that yields typically a 100 dB signal to noise
ratio– the best in the market. All of the overall gain is in this single stage.
This significantly reduces phase distortion and yields a dynamic, stable
soundstage with terrific dimensionality.

Input Tube- The input tube can be “rolled”
between a 12AU7, a 12AX7 or a 12AV7 to maximize gain and listening preferences.
Each unit ships with a set of 12AU7s and 12AX7s.

MM/MC- Selectable inputs for either moving
magnet or moving coil cartridge designs

Matching Input Transformer- The MC input
utilizes a matching input transformer to optimize the impedance match between a
MC cartridge and the amplifier input regardless of the interconnect cable
variances.

Loading Controls- Front panel controls
allow the user to set resistive and capacitive loading to match our custom
transformer input

Voltage Meter- Illuminated front panel
INDEPENDENT voltage meters allow for quick diagnosis and resolution of
cartridge imbalances

Output Stage- Our proprietary output stage
design uses a 6GH8 the only one in the industry that provides ultimate signal
linearity regardless of interconnect cable variances.

Mute Switch- We have designed a front panel
mute switch so that your amplifier gain does not requireadjustment between
record changes

Aviation Grade Chassis- All amplifier
chassis are aviation grade aluminum with a mutiphase powdercoat and clear coat
finish. The amplifier finish is absolutely beautiful and bulletproof! The front
panels are machined from solid blocks of aviation grade aluminum. The entire
amplifier is assembled using Military Standard stainless steel hardware for
ultimate reliability and a lifetime of trouble free service. All hardware is
meticulously staked using an aerospace coating to eliminate any hardware
failures over time through vibration, shipping or movement. This is an assembly
process honed over many years of satellite manufacturing and assembly where
re-tightening hardware can’t happen.

Internal Wiring- The entire amplifier is
wired using 18 gauge Military Standard 16878 teflon coated, silverplated copper
wire. This is the same wire used for the Navy’s Aegis Cruisers! Heat is the
enemy of amplifier reliability. Because this is a Class A design, there is some
heating of the unit which causes the wiring to age and degrade over time. Our
wire never ages. The teflon coating will last a lifetime. The interior of your
amplifier will look the same in 10 years as it looks coming off of the
production line. The amplifier is designed using all 18 gauge wire to provide
many times more the current density than can be achieved using printed wire
boards or lower quality wiring.

 

Burn-In Process- Each amplifier undergoes a
rigorous 100 hour burn-in prior to acceptance testing. This drives out any
component infant mortality problems and ages each amplifier into it’s perfect
listening range.

Manufacturing Process- All amplifiers are
built using our own Statistical Process Control manufacturing processes that
yield better than a 99.8% first pass yield. This is better than the airline
industry’s or hospitals’ safety record. The finished amplifier is 100%
reliable, tested and guaranteed for a lifetime.

Power Measurement System- Each amplifier
has a tuned, power measurement system that allows for flawless system integration
and adjustment.

Shipping- Each amplifier is shipped using a 2
box, double wall container system that has diecut, high density and low density
foam vibration absorption material. This shipping system is designed to
withstand a drop on all 6 box sides from 3 feet and produce no amplifier
damage. We have NEVER had an amplifier returned for shipping damage.
