I prefer the latter because this allows the bias resistor to do double-duty by isolating the valve from load capacitance somewhat, Or in the case of the self-biased circuit from the junction of the bias resistor Rb and load resistor Rk ('Out2'). The output may be taken directly from the cathode ('Out1' in the diagram), It is normally used only as a tonally transparent buffer stage, such as for driving the output of an effects loop, for example. The AC-coupled version is not so useful for this since the input couling cap prevents the flow of quiescent grid current. However, whereas the DC-Coupled cathode follower can produce a unique sort of overdrive, It also has low output resistance, so wide bandwidth can be maintained when driving heavy capacitive loads like long cable runs. The cathode follower has very high input resistance, and low input capacitance because it does not suffer from the Miller effect.
So the second one does not cause loss of gain or increased distortion by loading down the first one. This speaker’s distinctively smooth character remains sweet, no matter how hard you push it, delivering a full bodied woody tone has no equal in the world of guitar speakers.The cathode follower is normally used as a buffer between a one bit of circuit and another, The HP12 speaker is a unique driver that combines the exceptional clarity and treble extension of the Supro DT12 speaker, with superior power handling due to a larger magnet and a hemp cone. The Jupiter amp comes equipped with a brand-new, state of the art, USA made HP12 speaker that was designed specifically for this model. Since the tremolo is performed by modulating the bias of the output tubes, the reverb necessarily comes before the tremolo effect, for a mesmerizing combination of pure tube reverb and tremolo when both effects are combined. The grid bias tremolo is gives a much deeper, stronger and more pronounced throbbing effect. 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. 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 switchable power amp topology of the Jupiter not only allows for players to change the texture and 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 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 Jupiter model features our unique switchable rectifier topology, allowing musicians to select 35-Watts (Class A) or 45 / 60 watts (Class AB) to suit the gig at hand.
