Join us as we take a deep dive into this fascinating TMK 7TR-800 transistor radio from around 1960. While it looks and feels like a Toshiba or Hitachi model, the true manufacturer and history are a bit of a mystery!
This upper-end shirt-pocket radio features a sleek horizontal design and is a two-band model (AM/Medium Wave and Shortwave). We open it up to examine the internal construction, including the:
• 🔍 High-quality build and tight component placement.
• 💡 Toshiba-branded transistors and insulated wiring.
• 🤔 The curious chrome disk on the bottom—a blank for an optional tripod stand?
We also uncover a clue inside: the name Toyomenka, Inc., leading to the theory that "TMK" might be derived from the U.S. importer/sales agent. Discover the intriguing backstory of this beautiful piece of vintage electronics and Japanese manufacturing from the early 1960s!
