Quick view

The Toshiba 13A25 is a vintage analog television set introduced in the early 1970s, featuring a black and white display with a CRT (Cathode Ray Tube) technology. It operates on standard analog broadcast signals and includes manual tuning controls for channel selection. The set typically has a screen size of approximately 13 inches diagonally, suitable for home entertainment of the era. Power supply requirements adhere to AC mains voltage common in the region of sale, typically 100-120V or 220-240V. The chassis and circuit design are based on vacuum tube and early transistor technology, reflecting the transitional phase in TV manufacturing. The unit's connectors are minimalistic, generally including antenna input for terrestrial broadcast reception and basic audio-video interfaces if applicable.

The television's internal components comprise an RF tuner, intermediate frequency stages, video and audio amplifiers, and CRT driver circuits. The mechanical controls include rotary dials for channel selection and volume, along with contrast and brightness adjustments. The television lacks remote control functionality, as this was not standard at the time. Power consumption is modest compared to modern TVs but higher than later solid-state models.

The Toshiba 13A25 offers a compact and reliable CRT display known for its sharp black and white picture rendering. Its solid mechanical design ensures durability and longevity in use. The analog tuning system allows for precise manual control over channel selection. The television uses universally accepted power input, making it versatile across different regions with appropriate voltage. Its simplicity in design allows easy maintenance and repair by technicians familiar with vintage electronics. Moreover, it represents a classic piece of technology that is of interest to collectors and vintage electronics enthusiasts.

The Toshiba 13A25 lacks color display capabilities, limiting it to black and white images only. Its analog tuning makes channel surfing slower and less convenient compared to modern digital TVs. The television consumes more power and generates more heat compared to contemporary models. It does not support modern input interfaces such as HDMI or USB, restricting connectivity options. The picture quality may suffer from screen flicker and lower resolution inherent to CRT technology. Additionally, the bulky chassis and heavy weight reduce its portability and space efficiency.
