Sony LAM-Z03

Sony CD/MD combo PC speaker bookshelf system. Works as PC speakers over USB, and will also work as a netMD recorder after switching modes. Will work as PC speakers and with Sonicstage on Windows 10.

Can write discs through netMD using Sony's SonicStage or OpenMG software. Device playback can also be controlled using these programs. Can also record to MD from a CD directly at 4x speed.

Recently, support has been added for all LAM Series decks to web minidisc. This device has been tested and works completely without issue. You can also usePlatinum-MD v 1.2.0 or later to write discs (though it is quite buggy).

Some people have modified/refurbished their units to improve sound quality Part 1 and Part 2.

Remote model: Sony RMT-CL03

The amplifier for the speakers is located inside of the left speaker. In case you want to replace the capacitors on the amplifier PCB, the specifications are as follows:

Identifier Type Capacitance Voltage Diameter Length
C155 electrolytic, radial 1 µF 50 V 5 mm 10 mm
C157 electrolytic, radial 47 µF 10 V 5 mm 10 mm
C158 electrolytic, radial 220 µF 10 V 5 mm 10 mm
C160 electrolytic, radial 2200 µF 10 V 10 mm 20 mm
C255 electrolytic, radial 1 µF 50 V 5 mm 10 mm
C257 electrolytic, radial 47 µF 10 V 5 mm 10 mm
C258 electrolytic, radial 220 µF 10 V 5 mm 10 mm
C260 electrolytic, radial 2200 µF 10 V 10 mm 20 mm
C351 electrolytic, radial 47 µF 10 V 5 mm 10 mm
C352 electrolytic, radial 10 µF 50 V 5 mm 10 mm
C353 electrolytic, radial 1000 µF 16 V 10 mm 16 mm

There is an additional capacitor inside of each speaker, in line between the main driver and the tweeter. The specifications are as follows:

Identifier Type Capacitance Voltage Diameter Length
N/A bipolar electrolytic, axial 1 µF 50 V 6 mm 17 mm

Note: bipolar electrolytic capacitors of this type are somewhat hard to find. Alternatively, a polypropylene film capacitor should make a suitable replacement and may, in fact, offer superior audio characteristics.1)
