Supro 1820RBB Delta King 10 Combo

The Supro Delta King 10 brings tube tone and reverb to a compact space

The Supro 1820RBB Delta King 10 Combo is a 5-watt tube amplifier with straightforward controls and built-in reverb. For guitarists looking for their first tube combo, it puts essential tone controls right at your fingertips. The combination of a 10-inch Supro DK10 speaker and a Master volume control makes it easy to work with your amp sound at home or in a smaller rehearsal space.

The 12AX7 preamp tube and 6V6 power tube form the heart of this compact combo. You use Volume and Master to control the amplifier signal, while Treble and Bass help tailor the tone to your guitar. The built-in Reverb adds space to individual notes and chords. You can use it subtly for a little extra depth, or dial it in more prominently when you’re looking for a more spacious atmosphere.

The controls remain intentionally simple: aside from Volume, Treble, Bass, Reverb, and Master, you don't need to navigate any complicated settings. The amplifier has a Line-Out connection and no effects loop. With 5 watts of power and its custom 10-inch speaker, this is a practical tube combo to get to know at home, during practice, or for small-scale jam sessions. The provided specifications list one 12AX7 in the preamp and one 6V6 in the power stage.

The cabinet is made of poplar and finished with black tolex. Measuring 41 x 18 x 38 cm and weighing 10.5 kg, the Delta King 10 remains compact enough to place and move with ease. This Supro combines tube amplification, reverb, and an intuitive, easy-to-understand layout in one package. A great way to take your first steps with a tube combo and discover your own settings.
