MATCHLESS
MUSICAL INSTRUMENT AMPLIFIER
For All Avalon 30 and 35 models
INTRODUCTION
Thank you for choosing a MATCHLESS brand instrument amplifier. Your amplifier has
been carefully hand-crafted using only quality materials. The chassis of your amplifier is
completely hand wired employing construction techniques of military electronics
manufacturers. We utilize a Hybrid method of point to point wiring, turret style, and printed
circuit board. The board in the Avalon series utilizes 3 oz. copper tracing.
The wiring is silver coated stranded copper in a Teflon jacket for extra resistance to heat
and
decay. We use chassis mount tube sockets that are rivet mounted to a rugged welded
steel chassis. Our hand wired paper bobbin transformers are designed for 100% duty cycle.
Vacuum tubes are selected for tone, low noise and performance. This kind of craftsmanship
and attention to detail enables us to offer to the purchaser our six year guarantee.
MATCHLESS amplifiers are ruggedly built, and aside from the periodic tube or indicator
lamp replacement, should require very little maintenance. We have designed every
MATCHLESS product to be a trouble-free, roadworthy, studio quality amplifier.
FEATURES
Your MATCHLESS is a straight forward amplifier devoid of bells and whistles. It is
an all tube design including the power supply rectifier. Cathode bias operation is utilized for
the output stage. The top-
boost channel uses two 12AX7’s tubes in the first preamplifier.
All Avalon amplifiers incorporate a
MASTER
volume control feature. Only 30 Watt EL-84
based Avalon amplifiers will come standard with a
HI-LO
power setting switch enabling the
artist to take full advantage of the harmonic rich nature of
an all vacuum tube design.
An effects loop is a standard option for the Avalon series. MATCHLESS
Avalon
amplifiers
may be ordered as single combo speaker as well as separate head and
cabinet
configuration.
OPERATION: GENERAL
Your MATCHLESS is an all tube design. If your experience is limited with regard to vacuum
tube instruments amplifiers, you should become familiar with the characteristics that
differentiate vacuum tube designs from their solid-
state counterparts…
Aside from the
tone
and sonic performance.
1. Vacuum tube amplifiers require a “warm up” period of up to one minute before they
become operational, and they usually sound better as they “cook”. This is due to the fact
that electrons only flow when the
cathode
of a tube if fully
heated
. This is also the reason
vacuum tube amplifiers run so much hotter than solid-state design.
2. Many vacuum tube amplifiers incorporate a STAND-BY switch, which aside from muting
the amplifier, performs a more valuable function of removing current from the circuit while
