Matchless DC30 in the background (at the bottom left)

This amplifier was used during 1999. [watch]

The DC30 is Matchless's first design and it is still produced.

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 learn to prefer. Also included is a high treble cut control and 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 or 16 ohms) and a speaker phase-reverse switch.
