SUPRO S6420+ THUNDERBOLT+ GUITAR AMPLIFIER
The S6420+ takes the already fantastic Thunderbolt and adds even MORE flexibility with the option of the original 35-Watt “Class A” Cathode bias, 45-Watt “Class AB” Grid Bias, and 60-Watt “Class AB” Silicon rectification. Otherwise, it’s the same amp you’ll love: pair of 6L6 output tubes, 15” Supro speaker, Blue Rhino Hide Tolex, and assembled in the USA!
