ECC83 S4A Dynamic – this tube provides speed, remains balanced, low-distortion and is a lot of fun

12AX7B Shuguang – this tube delivers attack, pressure and real fun with rock and fast beats – price tip

12AX7LPS Sovtek – great attack, good detail, a slightly brighter and more open tone, with well-controlled bass
