Up for your consideration today are a pair of RARE Audio Classics. This is for BOTH units. NO CHERRY PICKING of one and not the other. Consider them siblings that need adoption together into a loving family. Below is the description from the service manuals.
MCLAREN 602 Control Preampliﬁer
The McLaren 602 component series represents a unique synthesis of art, science and technology — the realization of a design philosophy dedicated simply to the accurate reproduction of music.
Form, function and performance specifications all express and testify to this basic ideal. But most important is the innate ability of the range to recreate a true musical experience.
The McLaren 602 is a high gain, high resolution “straight line" preamplifier, fully compatible with a wide range of signal sources from low output moving coil cartridges to high output CD players. Phono gain can be switched for either moving or fixed coil cartridges. Provision is made for optimum cartridge loading. An input buffer precedes the two-stage passive/active RIAA equalization where particular care and attention has been given to achieving both amplitude and phase accuracy, not only in absolute terms, but to ensure precise matching between channels.
Power supply design also makes a major contribution to performance. Individual stages of each channel have their own locally regulated supplies fed from a central regulated supply incorporating a heavy duty shielded toroidal transformer. A shielded AC power cord reduces unwanted interference from external sources.
As a result the 602 possesses superlative dynamic and imaging qualities ~ clearly focused detail revealing the most subtle instrumental and vocal timbres, with a true perception of image depth
and height. The high undistorted output voltage capability of the line stage with an unusually low output impedance, ensures that the 602 will fully drive any power amplifier even via extreme lengths of shielded cable.
Construction is to the highest engineering standards. The case is entirely non-ferrous — face plate and side blocks are out and machined from proprietary extruded sections, top and bottom
covers coated with an attractive and durable textured finish. Front fixing screws, nameplate and all input and output sockets on the rear panel are 24-karat gold plated. Control knobs are turned from solid aluminum, satin anodized to harmonize with the front panel. Internal construction features gain selected semiconductors and highest quality passive components, mounted on a double-sided military
grade glass epoxy board. The precision film Potentiometers and sealed switches with self-wiping contacts have been chosen not only for their sonic excellence, but also for their smooth precise action and tactile qualities.

The McLaren 602 is a "straight line" preamplifier, with facilities for accepting moving coil or moving magnet cartridges, as well as five high level inputs, including two tape inputs and a dedicated CD input.
The Phono input provides 60 (MM) or 80dB (MC) of gain (from input to output of the preamplifier) at 1kHz. The stage is split into two active gain blocks, the first has a flat Frequency response and switchable gain. The second incorporates the RIAA equalization as well as some further gain.
An extra set of Phono sockets is provided at the input to allow the Phono cartridge being used to be loaded appropriately.
The high level inputs provide 20dB of gain (max) with a flat
frequency response. Volume and balance controls are also provided
in this stage,
Two tape record outputs are also provided. Record signal is
selected by means of a second selector switch completely
independent of the input selector. This switching is done at high
level and no amplification is provided between the tuner, CD, Aux or
tape inputs and the record output.
MCLAREN 702 Dual Channel Power Amplifier
The McLaren 702 Dual Channel
Power Amplifier represents a significant advance in the application of Power MOSFETs.
Over 200 Watts (320 into 4 ohms) of Pure Power in an Elegant, Conveniently Sized Package. Designed and engineered for the most critical applications, it raises solid state amplifier technology to a new performance level. Increasing recognition is now being given to the superiority of Power MOSFETs over bipolar power transistors. Briefly, they offer the following advantages:
under all operating conditions.
performance — faster and more
accurate transient response and
wider bandwidth at all power
the need for thermal sensors,
relays or limiting circuitry.
unpleasant odd-order harmonics,
as the onset of clipping is
topology with fewer active
devices in the signal path and
lower negative feedback.
The successful application of Power MOSFETs in the McLaren 702 however, has been achieved not
merely through careful attention to circuit design and layout, but from a critical analysis of the dynamic and interactive operating conditions within the output, driver and pre-driver stages. The result is a power amplifier possessing quite special qualities--natural, effortless reproduction of dynamics with an unusually accurate resolution of fine detail, harmonic structure and ambient information.
Construction and inter-wiring employ the highest quality materials, components and craftsmanship. The case is entirely non-ferrous. Face plate and side blocks are cut and machined from proprietary extruded sections, then hand finished and anodized. A single alloy casting forms the mounting bracket for the output devices and the external finned heatsink heat flow is not impeded by poor metal to metal surface contact or mechanical fastenings.
Top and bottom covers are coated with an attractive and durable textured finish. Front fixing screws,
nameplate and input connectors are all 24-karat gold plated.
