Rare & clean, all original 1965 Airline model 62-9020A branded Supro Thunderbolt S6420 amplifier, in unbelievable electronic and cosmetic shape- impossible to find in this condition! Sounds fantastic & strong.
Made by Valco in Chicago, Illinois, with unique Airline black & white tuxedo style cabinet detailing rather than standard Supro Thunderbolt cabinet, but exactly the same amplifier.
Original big Jensen C15-PS 15" gold-label speaker #220509 (manufactured 9th month of 1965) in perfect condition. Excellent chrome amp chassis, not rusted as typical of this vintage.
New Old Stock RCA 6L6 power tubes, 12AX7 preamp tubes, and 5U4 tube rectifier (before switch to solid state rectifier), original transformers & circuit, original power cord, handle, and rubber feet.
Solid pine finger-jointed cabinet is in amazing condition, with black & white tuxedo ostrich-texture vinyl covering.
Original & cool Airline badge and grille cloth are perfect- even original spare fuse envelope stapled inside cabinet!
Very rare and fine example of the renowned Airline/Supro Thunderbolt amp. Gorgeous tone and breakup, classic Thunderbolt sound when played clean or cranked.
This is a ferocious and beautiful amp that is almost perfect in every way.
Rare opportunity to own and play this special amplifier. Collectible and will increase in value.
