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

Repair
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)
