This is what changed the amp world. The DC-30 was the company’s first
design and still leads the lineup. Thirty very conservatively rated watts from
a quartet of EL-84’s, through two channels, each with unique voicing and tone
control layouts, produce a world of tone choices. True "Class A” configuration
gives rich, complex harmonics whether played clean, mildly overdriven, or with
all out power tube saturation. This means you should sound great in any situation,
in any music style.
A long list of musician designed features includes: highly interactive tone
controls and circuitries unique to each channel, bypassable master volume,
individual channel effects loops, cut control for high frequency shaping, high
and low (30 or 15 watt) power settings, selectable output impedance and phase
inverter switches allow the use of additional speaker cabinets or amps in-phase
with the DC-30.
The preamp sections are based on a layout of two 12AX7's in Channel 1 and
one EF86 in Channel 2. The two 12AX7's in Channel 1 create a parallel-triode
circuit with interactive bass and treble. The one EF86 in Channel 2 consists of
a high-gain pentode coupled to a six-position tone switch. Outright benefits
include quick dial-in of new tones and an easy return to the settings you
prefer. Also "high treble" cut control, master volume, with a bypass
feature that offers flexible control of the power amp section. The power amp is
fed by a 12AX7 phase inverter, which drives four EL84 power tubes. The
rectifier circuit gives you the flexibility of using one 5AR4 for a quick
attack or you can use two 5V4's for a smooth, round response. Other
professional features include an effects loop, half power-mode switch (a
conservative 30 watts switching to 15 watts), output impedance selector (4, 8,
16 ohms) and a speaker phase-reverse switch.
Sound
on the 212 Combo is delivered through two dissimilar Celestion speakers: a
G12H30 and a Greenback 25, each specially modified through a proprietary
MATCHLESS formula. All of this is encased in an extremely sturdy hand-made
11-ply, ¾” Baltic birch cabinet, wrapped in richly textured black vinyl. The
finishing touch is our signature backlit nameplate and control panel, which
lets you (and the audience) know when the power is on.
