The Matchless DC-30 Tube Set consists of 3 x 12AX7, 4 x EL84 Power tubes (Matched Quad) , 1 x EF86 Preamp Tube and 1 5AR4 Rectifier.
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.
