Found over on TechWeek, the Rarest and Most Awesome Boomboxes of The 80's, 2/22/21 https://www.techweekmag.com/news/speakers/rarest-and-most-awesome-boomboxes-of-the-1980s/
An interesting ad for Ocean Radio (Singapore). Quote "Keen business acumen brought about the establishment of Conion Electronics, a manufacturing concern." From The Straits Times (Singapore) 1984 I've been posting some Conion Boomboxes in the newspaper ad thread and found this information.
Found this article on Amcol 1985 from the Singapore Monitor. I found a new to me brand, Amcol Boomboxes, it looks like they distributed Sony and also owned Sankei.
Asahi Spending $20M on Factory and Robots, Biz Times (Singapore) 1982 Asahi made both Asahi and Fairmate Products.
Turbo Sound That's Made in Singapore, Singapore Monitor 1983, 15 watts, that's pretty nice for a boomer. This looks nicer than the Magnovox USA Versions we used to see.
