Jupiter Condenser, one of the main brands specialized in it. Model 88 is also one of the rare pieces of equipment that uses brass as the main material for its chassis (a material that is much more expensive than aluminum or steel), something that due to its diamagnetic characteristics, has the capacity to generate inverted magnetic fields at its interior that can cancel external ones. - Page 4 Furthermore, it is a concept that has been successfully used in many other fields: the stability of a helicopter, for example, is achieved by devices that generate asymmetric forces. The ASTAT concept makes Model 88 one of the rare single-ended class a1 tube amplifiers to reach its power range reliably and stably.

(black/white: left channel; red: right channel), the speaker cables to the appropriate binding posts (taking care to put both with the same polarities). Finally connect the power cord to the IEC connector, respecting the nominal voltage of your Model 88 (120V or 230V). -
Page 6: Turning On Your Model M88
Turning on your Model 88 On its top panel, Model 88 has two potentiometers surrounded by LED rings and two toggle switches over them. These potentiometers are the Timbre Lock® adjustments, one of the truly unique features of Audiopax products. Before turning on the equipment for the first time, set all adjustments (two on each monoblock) to their minimum position, ie fully counterclockwise. -
Page 7: The Timbre Lock
® The Timbre Lock is an Audiopax invention that allows the best possible match of the distortion behavior of their amplifiers with any of their speakers, resulting in the best distortion spectrum for the system as a whole (we can consider it as an “adjustment to the lowest system distortion”). - Page 8 (you certainly will always get the most of it with these amplifiers), Model 88 has red LEDs that are a clear indication that you are approaching dangerous presets regarding your tube's life. So, they should never be used as a preset position.

Page 10: Model M88 As An Inverter Amplifier
Model 88 as an inverter amplifier Model 88 is a phase inversion amplifier and, depending on the other components of your system, perhaps the best sound result will occur with the normal phase. In this case, reverse the phase in any component containing this feature or at the speakers' cables, inverting on both channels the polarity of one of the ends (amplifiers or speakers) to achieve the best possible performance. -
