This is what changed the amp world. The DC-30 was Matchless first design and still leads the lineup. Thirty conservatively rated watts from a quartet of EL-84s, through two channels—each with unique voicing and tone control layouts—produce a world of tonal choices. The true “Class A” configuration delivers rich, complex harmonics, whether played clean, mildly overdriven, or with full power tube saturation. This ensures you sound great in any situation, across all musical styles.

A long list of musician-designed features includes highly interactive tone controls and circuitries unique to each channel, a bypassable master volume, individual channel effects loops, a cut control for high-frequency shaping, high and low (30- or 15-watt) power settings, and selectable output impedance. The phase inverter switches allow the use of additional speaker cabinets or amps in-phase with the DC-30.

The preamp sections are based on two 12AX7s in Channel 1 and one EF86 in Channel 2. The two 12AX7s in Channel 1 create a parallel-triode circuit with interactive bass and treble controls. The EF86 in Channel 2 consists of a high-gain pentode coupled to a six-position tone switch. The benefits include quick dialing of new tones and an easy return to your preferred settings. Additional features include a “high treble” cut control and a master volume with a bypass feature, offering 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 option of using a single 5AR4 for a quick attack or two 5V4s for a smoother, rounder response.

Other professional features include an effects loop, a half-power mode switch (a conservative 30 watts switching to 15 watts), an output impedance selector (4, 8, 16 ohms), and a speaker phase-reverse switch.

Sound from the 212 Combo is delivered through two dissimilar 8 Ohm Celestion speakers: a G12H-30 and a G12M Green Back wired parallel in a 4 Ohm Load. 

All of this is housed in an extremely sturdy, hand-made 11-ply, 3/4” Baltic birch cabinet, wrapped in richly textured black vinyl. The finishing touch is the signature Matchless backlit nameplate, which lets you (and the audience) know when the power is on.

In excellent condition, tested and working fine, comes with official footswitch but it can be temperemental, i use another footswitch which works fine, collection preferable as its very heavy but can post.
