Reviving the Legend: Modifying Pioneer CT-A9 with a 220V “Golden Heart” in Cambodia

Prologue: Slow Mornings and Fast Connections
Perhaps the morning sun hasn’t awakened many tourists yet, as the internet speed in Siem Reap is surprisingly fast. Under Cellcard’s 4G network, I clocked in at 156 Mbps. While 5G billboards line the streets, this “good enough” 4G is the perfect backbone for publishing this long post about “slow living”—discussing analog tapes that have been spinning for 40 years amidst this digital high-speed era.
The lightning-fast speed of Cellcard 4G in Siem Reap at dawn is good enough.
Part 1: The Gamble of a Bargain and Cross-Border “Archaeology”
Bluetooth speakers are convenient enough to make one feel numb. Only “old souls” like me would tinker with these heavy metal hunks. It’s not for the lossless audio, but for the thrill of restoration. This obsession is about settling a childhood debt from an era when we only had cassettes and couldn’t afford the gear we dreamed of.
Two years ago, I scored this Pioneer CT-A9 for $300 with a blown transformer. The seller had stuffed a disconnected “Bando” transformer with a ridiculous knob into the slot just for show. This wasn’t just buying hardware; it was purchasing a touchable piece of industrial history.
Ritual: Unfolding the Reiwa 4 Time Capsule
A $50 shipping fee brought a package stuffed with dozens of Japanese newspapers. One bundle was dated “Reiwa 4 (June 21, 2022).” They didn’t just cushion the vibration; they felt like fragments of the analog era sent across time and space.
A Japanese newspaper dated June 21, 2022, is the best physical evidence of leaving one’s homeland.
Part 2: Mazes and Respect: The Obsession with Replicating CT-A1。
Many ask why I drive myself crazy drawing schematics on JLCPCB for an 80s circuit. Just look at the wreckage of this Pioneer CT-A1. The transformer is gone, boards are snapped, and drivers are missing.
I tried to replicate its control circuits, attempting to patch these broken “industrial genes” with modern PCB technology. But faced with the jungle of point-to-point wiring, I felt a deep reverence for the terrifying complexity of the discrete component era. This respect for the peak of industrial design far outweighs the joy of listening.

Part 3: Survival Philosophy: Saving the “Out-of-Print” Soul
In Phnom Penh, the risk of plugging into the wrong voltage is everywhere. I once accidentally fried a 100V fan by plugging it into a 220V socket. To protect this legend, I chose a “heart transplant.”
Replacing a transformer (the Golden R-Core) costs only a few dozen dollars, but if you fry that out-of-print HA12058NT logic chip or the AUTO BLE CPU, this flagship becomes scrap metal. Protecting the chip (the soul) is the ultimate expression of love.
Preserving the chip is preserving its life.
Part 4:A Serendipitous Encounter in Phnom Penh: The Warm Yellow Hands in an Alleyway
While wandering the streets of Phnom Penh, I passed a house and inadvertently caught sight of a Pioneer CT-9 on the living room counter. Its distinctive silver panel immediately identified it as a 1978 classic.
According to the Audio Heritage Yearbook, this machine cost a whopping 95,000 yen back then. In an era when average wages were low, it was an absolute luxury. Decades later in Phnom Penh, its ticking hands still tell the story of the analog era’s glory.
Part 5:Epilogue: Recording Eagles—Letting the Meteors Dance Again
As an Eagles fan, the A9’s AUTO BLE calibration system felt tailor-made for me. I recorded multiple versions of “Hotel California”—from Houston in ’77 to Frozen Territory in ’94.
What fascinates me most is the A9’s wide, elongated level meter. Although I’m not a professional recording engineer, recording music like “New Kid in Town” on a machine I’ve personally repaired and tuned feels like the lyrics say: “Great expectations, everybody’s watching you…”
Current Status: Two years ago, this A9 was fully revived. Now, it sits quietly in its case, peacefully collecting dust. I don’t open it often, but as long as it’s there, I know the story of redemption, the $300 gamble, and the Japanese newspaper is complete.
Conclusion: I’m not a repair expert; I’m just an ordinary enthusiast “forced” out by these old things. All this tinkering, listening to the sound of the tape slowly turning, was worth it.
Let the shooting stars beat again: New Kid in Town.
