TONE

INTRODUCTION

Thank you for choosing the Palmer FAB5.

Your new amp is an all-tube amplifier with a Class-A design that is espe-

cially prized by countless guitarists because of its direct response and

harmonious distortion and is frequently used to record guitar tracks in

the studio. Because of their seemingly low output, single-ended amplifi-

ers are usually pigeon-holed in the practice amp category. In conjunc-

tion with the powerful, built-in 10" Eminence Ragin Cajun speaker or an

external speaker cabinet, however, the FAB5's 5 watts reach volume levels

that are thoroughly band- and stage-compatible. Here, it is above all

at high volume levels that the power stage distortion and natural com-

pression preferred by tone aficionados come into their own. These can be

controlled conveniently by means of picking dynamics and with the guitar

volume control. The boost control lets you continually boost the volume

and distortion yet again. This function can be activated via an addition-

al footswitch for various rhythm and solo settings.

In keeping with the practice amp application, one special feature of FAB5

is a built-in power attenuator capable of reducing the volume to a level

acceptable in living rooms and bedrooms. This allows you to use the over-

drive of the amp even at drastically reduced levels without alarming your

neighbours or the police.

The FAB5 is built using high-quality components and specially selected

tubes that ensure maximum tone quality and reliable operation. The preamp

uses a 12AX7 (ECC83) tube and the output stage a 6V6; the rectifier is

an EZ81. If you should ever notice signs of wear such as high frequency

loss, reduced output, hum or microphonics, have the tubes replaced only

by a qualified technician.

We hope you have a lot of fun with your Palmer FAB5!

1) BEFORE SWITCHING THE AMP ON FOR THE FIRST TIME

—Make certain that the voltage selected next to the rear panel pow-

er connector of the FAB5 (mains voltage selector) matches the mains

voltage in your country.

—Make certain that the amp is positioned safely and secured.

—Ensure sufficient air circulation through the cooling slits of the

FAB5.

PLEASE MAKE CERTAIN THAT YOU READ ALL OF THE SAFETY INSTRUCTIONS CON-

TAINED IN THIS MANUAL BEFORE YOU BEGIN USING YOUR FAB5!

2) SINGLE-ENDED OR PUSH-PULL

Like tube and diode rectifiers, both "single-ended and "push-pull" am-

plifiers have a fixed place among guitarists because of their varying

tone characteristics. Both terms actually refer only to the output stage.

Single-ended amplifiers produce a complex, warm tone with distinctive

harmonics, while push-pull amplifiers stand out because of high efficien-

cy, direct response, and high dynamics.

Single-ended circuits usually use only one power tube (or multiple tubes

connected in parallel for higher output). They always run at full power

regardless of whether or not an input signal is present - in other words,

the power tube is always "on". This mode of operation is also called

"Class A".

The push-pull circuit requires a pair of power tubes (or multiple pairs

connected in parallel for higher output). The input signal of a push-pull

amplifier is split into a signal with the same phase as the original and

a signal with the phase reversed by 180°. The two opposing signals now

drive the power tubes alternately, i.e., while one tube amplifies the

in-phase signal ("on"), the tube driven by the phase-reversed signal is

"off". The difference between the two sides is picked up as the output

signal. For this reason, push-pull amplifiers are also referred to as

differential amplifiers. They are usually operated in "Class AB".

The constant alternation produces distortion in the transition area

("on", "off"). Many guitarists love this aggressive, scratchy transition

distortion.

Unlike the single-ended circuit ("always on"), the output transformer of

a push-pull amplifier is not constantly under load. This means that it is

less saturated and attains higher sound fidelity. Push-pull circuits are

also more efficient, since the rest periods of the power tubes ("off")

permit higher output levels when they are "on". However, odd overtones

generated in the output stage are cancelled out by the push-pull func-

tion, while they are clearly predominant in single-ended amplifiers.

In the end, the choice is a matter of taste. In the studio, professional

guitarists like to use small single-ended amplifiers, while more powerful

push-pull amplifiers are preferred on stage.

3) WHAT DOES A RECTIFIER DO?

The Palmer FAB5 has a EZ81 rectifier tube.

Rectifiers convert the alternating current from the mains connection into

direct current, which is required by the amplifier circuitry.

Early "classic" tube amplifiers used rectifier tubes that produce an

elastic feeling when playing. The advent of transistor technology result-

ed in the increasing use of silicon diodes as rectifiers, which produce

a direct, "crisp" response. They are cheaper, more efficient, and easi-

er to integrate in amplifier circuits than tube rectifiers are. Today,

one finds both tube and diode rectifiers in guitar amplifiers and has a

choice; many models even use diode rectifiers that emulate the response

and tone of a tube rectifier.

As a rule, diode rectifiers react more quickly to the high voltage re-

quirements of heavily played notes and chords. The significantly longer

rise time of a tube rectifier at first produces a voltage drop when the

strings(s) are plucked, which is often referred to as "sag" in English.

When the signal decays, the direct voltage increases again. This results

in essentially the same effect as that of a compressor/sustainer. Many

guitarists prefer tube rectifiers because of their quasi "breathing"

response and the possibility of controlling the tone by means of the at-

tack.

The maximum voltage and the rise time, i.e., the duration until the maxi-

mum voltage is generated, vary depending on the rectifier tube and type.

A different tube type or a diode plug-in that plugs into the tube socket

can change the playing feel, sound, and performance of an amplifier.

ALWAYS CONSULT A QUALIFIED TECHNICIAN BEFORE ANY CHANGE - A DIFFERENT

TUBE TYPE OR DIODE RECTIFIER COULD DAMAGE YOUR AMPLIFIER!

4) CONNECTIONS AND CONTROLS

CONTROL PANEL (TOP)

1INPUT

Connect your guitar to this socket. Use a high-quality instrument cable

for this.

2VOLUME

This control sets the volume of the FAB5. With single-coil pickups, light

distortion sets in at around the 12-o'clock position, with humbuckers a

little sooner; then the overdrive increases continuously. At very high

settings and with a strong attack, the amp produces the typical, harmoni-

ous Class-A crunch with light compression.

3TONE

This control sets the tone reproduction of the FAB5. At 0, the treble is

reduced, but the sound always remains defined and never becomes exces-

sively muffled or flabby. In the middle position the treble is largely

neutral, and turning the knob further to the right adds edge and pres-

ence.

4BOOST

This control is always activated unless a footswitch (see 11) is con-

nected and increases the volume and overdrive as it is turned to the the

right. In conjunction with the VOLUME control (1), it makes it possible

to adjust the level of distortion and volume of the FAB5 sensitively over

a wide range from clean to crunch to medium gain overdrive.

With a standard footswitch connected to the BOOST socket (11) on the rear

of the amplifier, the boost function can be activated or deactivated.

This makes it possible to set individual volume and distortion levels for

rhythm and solo playing and retrieve them with the footswitch.

5POWER LAMP

This indicator shows that the FAB5 is turned on and connected to a suit-

able power supply.
