Onkyo TA-2070 (1981–1984)
One of the most famous three-head cassette decks of its era, and a stealth contender against the Dragon.
Overview
Say you were building a high-end cassette setup in the early 1980s and didn't want to pay for a Nakamichi Dragon. The Onkyo TA-2070 was the deck that made sense. It wasn't flashy. It was a precision-engineered 3-head cassette deck, built like a vault and calibrated for serious tape users. Marketed internationally as the Onkyo Integra TA-2070, it arrived in 1981 and ran through 1984 as one of the brand's top-tier models.
Cassette decks were climbing toward audiophile legitimacy back then, and the TA-2070 was right in the middle of it. It supports Type I, CrO2, and Metal tapes, has Dolby B and C noise reduction, and reaches 21kHz on metal tape. Owners report that in blind comparisons with the Nakamichi Dragon the differences were minimal. One user said they "could barely tell any difference" and chose the Onkyo because the Dragon's auto-azimuth didn't justify the nearly $800 price gap ($900 vs. $1,700 at the time).
This is one of the most famous three-head decks Onkyo ever made, and it's a collector favorite. It was built in Japan with a dual capstan direct drive transport, Sendust heads, and Onkyo's proprietary Accubias auto-bias system. That gave it lab-grade calibration without requiring a degree in electronics.

Key Features
Sankyo Dual Capstan Transport
The core of the TA-2070 is its Sankyo Dual Capstan mechanism, a closed-loop dual transport. Owners confirm the tape transport is "undoubtedly very stabilized," and the 0.04% wow and flutter rating backs that up. Direct Drive on the capstan motor eliminates belt slippage and inertia issues, which means tighter speed control and cleaner high-frequency response. The design is borrowed from professional machines.
3-Head Sendust Configuration
The record, playback, and erase heads are separate, and all are made from Sendust, so the deck avoids the compromises of combo heads. Sendust offers excellent high-frequency response and durability, which suits metal tapes. The setup allows precise azimuth alignment and real-time monitoring during recording, which was a big deal for anyone making high-fidelity copies.
Accubias Auto-Bias & Calibration
Onkyo's Accubias system is an automatic bias calibration that takes the guesswork out of optimizing tape performance. You can run bias manually if you prefer, but the auto function gives consistent results across different tape types. That matters most for CrO2 and metal tapes, which demand precise bias settings. It saves you from needing a test oscillator and oscilloscope.
Precision Monitoring & Control
The front panel has a real-time tape counter with sensors on both reels, so you aren't guessing your position. There's also a metering device to monitor input and output levels, which helps avoid distortion during recording. Pitch control adjusts playback speed in fine increments, useful for DJs or musicians syncing to other sources. Despite the high-end specs, it stays simple: no auto-reverse and no digital displays.
Remote Capability & Build Quality
A wired remote control is included, handy in a multi-component setup. The deck weighs 9.5kg. The chassis is rigid, the buttons click with authority, and the whole unit feels made to last decades. Many have, assuming the belts haven't turned to gum.
Collectibility & Value
The Onkyo TA-2070 is very sought after by collectors, and it's one of the better decks Onkyo ever made. It never had the celebrity status of the Nakamichi Dragon, but it delivered 95% of the performance at half the price. Original pricing was around $700, with later market comparisons placing it at $900 against the Dragon's $1,700.
Current asking prices vary widely. A classified listing recently asked $300, while a wanted ad humorously offered $1. Units in working order with clean heads, fresh belts, and full calibration command a premium. The most commonly reported failure is the rewind belts. It's a routine maintenance item, but left alone it can strand your tapes mid-reel.
Service manuals, schematics, and repair guides are widely available online, from elektrotanya.com to hifi-manuals.com, so DIY fixes are very doable. It isn't a fragile museum piece. It's a working tool that rewards care and attention.
