The Hitachi TM-1081ZA or TM-1081ZB Seek & Scan AM radios came stock on the '70 and '71 model 240Zs. They have become quite expensive. I had a TM-1081ZA with all of the internals on the radio professionally refurbished that I sold on eBay for a best offer of $1,200.00 back in December. A lot of 240Z owners have installed the '72-'73 240Z Hitachi KM-1520CZ AM/FM radios in their '70 and '71 Zs, which are less than half of what the '70-'71 AM radios go for. It is commonly viewed as a period-correct upgrade since it also has FM and fits perfectly in the '70 and '71 240Zs. That's what I've decided to do with my two '71 240Zs.
Hello... I have the Hitachi radio out of a 8/71 build 240Z..
It is in great cosmetic shape. the light works and the auto search Operates smoothly. But there is occasional scratchy static in the volume control on the right.
Let me know
