Supro Thunderbolt S6420
SUPRO THUNDERBOLT S6420
The S6420 Thunderbolt is a 50th anniversary reissue of the 1964
Supro Thunderbolt 1x15 tube amplifier. Staying true to its vintage spec
with its cathode based 6L6 output section, the S6420 produces
35 watts of pure rock 'n' roll tone through a custom designed 15"
Supro TB15 speaker at a very affordable price.
Finished in an eye-catching 'Blue Rhino Hide' tolex, there is also the option of 3-way rectifier switching (35w/45w/60w) with the S6420+.
