Hi, I am looking to buy a vintage portable mono radio with a 2 way speaker (main speaker plus tweeter). It must have good FM reception and sound clear but not cheap and tinny. I've got my eye on a Toshiba RT-F452D but cannot find any info about it online. I zoomed in on the photo and it says made in Korea. Are Toshiba radios of this vintage any good (I'm guessing early 80's)?
