[ PRO SERVICED ] PS Audio 4.5 Preamplifier with power supply

The unit is in near perfect shape. Better image of the front coming.
The PS Audio Model 4.5 stereo preamplifier exemplifies the “minimalist” philosophy of hi-fi product design-the smallest number of circuit elements should be interposed between the program source and the power-amplifier/loudspeaker system - an absence of filters, tone controls, and similar response-altering features.
The PS Audio 4.5 consists basically of a phono-preamplifier/equalizer section, a fixed-gain line amplifier, and switching facilities.
The 4.5 features a STRAIGHTWIRE mode in which the line amplifier is completely bypassed. When high-level sources are played in this mode, the Model 4.5 is merely a passive switching center with a volume control. No active circuits come between the source and the preamplifier output, so virtually no distortion or noise is added to the program. Of course, phono operation requires a preamplifier/equalizer, and the Model 4.5 contains an excellent one, switchable by an internal slider between moving-magnet (mm) and moving-coil (mc) modes. The balance control differs from most in being an eleven-position switch that operates through precision (1 percent tolerance) resistors. The first two or three steps away from center change the balance in small increments, which become larger near the end of the control’s range. The large volume knob operates a high-quality multi-wiper volume control and has thirty-two mechanically detented positions. All components in the Model 4.5 were chosen for their high quality: 1 percent metal-film resistors, silver contact switches, gold loading-resistor sockets, polypropylene capacitors in the RIAA equalizer section, and matched FET phono-input stages. In this unit: - All electrolytic capacitors have been replaced. - All controls have been cleaned - The power supply has been modified with an AC On/Off switch since otherwise it stays always on and unplugging/plugging in is annoying. - The power connector from the AC power supply to the unit has been cleaned and reinforced.
