  • Modello: FM/MW/SW Stereo Cassette-Corder WA-8800 - Sony Corporation; Tokyo
  • Forma
  • Tascabile (portatile molto piccola), < 20 cm
  • Dimensioni (LxAxP)
  • 250 x 80 x 40 mm / 9.8 x 3.1 x 1.6 inch
  • Annotazioni

  • Portable travel radio and autoreverse stereo cassette recorder with alarm clock, shortwave coverage 49 - 13 m in 8 bands.

    This is a elaborated design and compact unit, using 7 x integrated circuits and 42 x transistors.

    The MW/FM bands are handled by a CX20111 AM/FM tuner IC and a TA7370F FM stereo MPX IC on FM. IF frequencies are 10.7MHz for FM and 455kHz for MW.

    The SW bands uses a RF front-end based on a 2SK238 FET and eight tuned RF coils. The 1st local oscillator uses a 2SC2223 and eight crystals (one per SW band). The 1st mixer uses another 2SC2223 and the 1st SW IF signal (10.7MHz) is filtered by a transformer and a ceramic filter before being passed to the CX20111 for further processing.

    The audio output is handled by a BA5208AF dual channel audio power amp IC. Stereo tape recording and playing uses a CX20023 stereo recorder/player pre-amp IC.

    The tape motor drive uses a CX20123 servo motor driver IC. A TC74HC00F 4 x NAND IC is used for system control, and a custom LCD401 IC handles the Clock/Counter and LCD display.

My radio unit came with the left speaker grille missing.

I have created a 3D print project on SCAD to replace the original part. While my design is not a exact replica becaue the 3D print machines in my planet region are not able to print a reliable part when specifying thiner walls and smaller holes, it is close to the original. 

The model was meant to be printed using cheap resin material, as it give the required precision.

After leting the printed model to cure under sinlight for a few days, I have painted it using spray paint.

This is the SCAD file contents (use SCAD and create a new project, then paste this text into it):
