Aiwa TP-802

The Aiwa TP-802 is a late-1960s portable open-reel tape recorder from Aiwa's TP-8xx series, introduced around 1969 as a step up from earlier suitcase models like the TP-801, targeting home users for speech, music dubbing, and mobile recording.​

Positioning and Era

Compact "lunchbox" design with improved electronics over the tube-hybrid TP-801, emphasizing dual-speed versatility in a battery/AC hybrid format for lectures, radio captures, and casual hi-fi listening.

Transport and Tape Format

• Reel size: Up to 5-7 inch reels.

• Drive system: Capstan drive with pinch roller and flywheel for better speed stability.

• Speeds: Two selectable: 3¾ ips and 7½ ips.

• Track format: Half-track mono (2-track, using both tape directions).

• Heads: 2-head configuration (erase + record/playback, permalloy cores).

Electronics and Performance

• Circuitry: Fully solid-state transistor amplifier (8-10 transistors typical), with manual record level, tone control, and tape counter.

• Power: 6V DC from 4× D-cells or AC mains (110-240V versions).

• Frequency response: Adequate for voice/light music (roughly 70Hz-10kHz at 7½ ips); modest SNR and wow/flutter (~0.15-0.2%) for portables.

• Speaker: Built-in 4x6 inch oval dynamic driver for monitoring.

Controls, I/O, and Features

• Transport: Play, Record, FF/Rewind, Stop buttons.

• Inputs/Outputs: Mic (high/low sensitivity), remote jack, earphone, aux line out, external speaker jack.

• Level meter (battery check function), possible AVC.

Construction and Dimensions

• Tabletop/portable plastic-metal case with handle; ~350 x 150 x 280 mm (WHD), 6-8 kg.

• Robust die-cast frame for transport durability.

Use and Restoration Notes

Strong performer at higher speed for vintage tapes; common fixes include pinch roller replacement, belt/idler refresh, capacitor recap, and head alignment. Collector favorite for reliable portable mechanics in the pre-cassette era
