Descrizione annuncio

Perfettamente funzionante e tenuto in ottime condizioni.
3 differenti vattaggi in classe A ed AB e 3 diverse "reazioni" del tremolo valvolare.
This top-of-the-line Supro amp.
The Jupiter model features our unique switchable rectifier topology, allowing musicians to select 35-Watts (Class A) or 45 / 60 watts (Class AB). The 35 watt cathode bias mode uses the legendary Thunderbolt power amp topology for a harmonically saturated, tube-rectified sound that combines wonderfully with this 1×12” platform. The 45 and 60 watt grid bias modes provide more volume and headroom as well as the faster transient response associated with Class AB power amps.
The switchable power amp topology of the Jupiter not only allows for players to change the texture and
output volume of the amp but it also provides two very different, all-tube tremolo effects depending on whether Class A (cathode bias) or Class AB (grid bias) mode is selected. The cathode bias tremolo is vintage Valco/Supro all the way, where the overall depth of the effect changes along with the dynamics of your playing. The grid bias tremolo is gives a much deeper, stronger and more pronounced throbbing effect.
The Jupiter amp comes equipped with a brand-new, state of the art, USA made HP12 speaker that was designed specifically for this model.
