Luxman CL350 & M-150 Power Amplifier

Electrical Disclaimer Further Information

These are the first Luxman solid state amplifiers.

The sound is very much the same as Luxman tube amplifiers, but with the reliability of solid state.

Both amplifiers have been checked by a qualified tech and everything is functional and they sound terrific!

Original packaging from 1972 is included!

CL350- The first control amplifier using transistors. Rosewood finish in perfect condition.

The equalizer circuit is based on a 3-stage direct-coupled circuit that combines PNP and NPN types, and the third stage adopts a push-pull operation method that combines PNP and NPN type transistors in a pair to increase the power supply utilization factor and ensure good linearity.

Low-level circuits, such as Phono and Mic, generally consist of a single equalizer amplifier, which selects the input terminal by switching three points : the input circuit, the output circuit and the equalization constant.
In CL350, each input terminal has its own amplifier and the input terminal is selected only on the output circuit side. This simplifies the wiring of the input circuit side and reduces the adverse effect of shield wires and shock noise at switching.

The tone control is an NF type LUX tone control, and the bending point frequency is a 3-step switching type for fine tone adjustment.
This circuit has a defeat switch and can be skipped if it is not used.

The high-cut and low-cut filters have two cut-off frequencies, so that noise can be attenuated while minimizing the effect on the program source.

The noise level is kept low by mainly composed of PNP type ultra-low noise silicon transistors which are easy to obtain a noise figure in general.

It has a built-in low frequency trimmer that adjusts the frequency band centered from 150 Hz to 300 Hz in seconds.
This circuit is located behind the equalizer circuit to reduce the effect on the recorded output.

A headphone amplifier with level control is built-in.
The circuit consists of a pure complimentary service circuit directly connected to all stages, with an output capacitor.

Equipped with an attenuator.

Phono1 terminal is equipped with impedance switching, and Phono2 is equipped with a socket for MC-type step-up transformer.
The Aux1 and 3 jacks are equipped with level sets.
