Vintage Supro Tone for Electric Guitar
The Supro 1822RTB Delta King 12 is a 15W tube combo amplifier built for players who want the sound that shaped early electric rock and the British Invasion. Its single-ended Class A 6L6 power amp and 12AX7 preamp deliver raw tonal character and touch sensitivity through a custom 12-inch DK12 speaker in a poplar cabinet.
Sustained Class A Tube Behaviour
The single-ended Class A design keeps the power tube conducting continuously, so the amplifier responds evenly during long passages without the compression shifts of push-pull circuits. Touch sensitivity remains consistent as the 6L6 delivers its full 15W into the DK12 speaker, preserving the dynamic relationship between picking attack and output.
15W 6L6 Power Decides Suitability
Fifteen watts of 6L6 tube power sets the headroom and volume ceiling for rehearsals, small venues and recording sessions. Players needing clean headroom at higher stage volumes or significantly more output will find this power level limiting. The 31.0000 kg weight also influences portability for frequent transport.
