even higher overall power output levels to try to solve the clipping problem. In reality,
we believe the most critical aspect is how fast a recovery an amplifier can achieve after
overload. With the incredible dynamics range of live and recorded music, even 2,000
watts of power is potentially not enough. Most of the music being listened to in an
average home listening room is only requiring about 1-3 watts of power. It is on the
transients of loud low frequency program material that tremendous signal voltages will
appear at the input of the amplifier. It is in this situation that the overload recovery
ability of an amplifier is of critical concern.
The Rocket 88 R extols its merits in the ability to handle transients and instantaneously
recover from brief or even extended overloads. The Rocket 88 R will overload
symmetrically at any frequency in the audio bandpass. It will also yield faithful
reproduction of extremely low frequencies at full output levels. The power transformer,
the power supply regulation and the output transformer design and careful shaping of
the overall frequency response curve all play a very important part in the ability of the
Rocket 88 R to recover quickly when overloaded. If one were to monitor the high
voltage rail voltage of the Rocket 88 R during soft and also loud music passages it would
be found there is no more than a volt or so change from soft to loud passages.
Another technical feature of your new Rocket 88 R amplifier is unconditional circuit
stability. The Rocket 88 R maybe operated with no load (without speaker) without
damage to the amplifier, output transformer or tubes.
Operating the Rocket 88 R stereo amplifier is a simple procedure since each unit is
designed for long term stability in virtually any home operating situation. Therefore, if
the unit is operated outside the parameters outlined in this owner’s manual, damage
may result. Please read this manual carefully before putting your new Rocket 88 R
amplifier in operation.
The following definitions are applicable to this manual. These definitions must be
followed explicitly.
