I had A Tandberg TCD- 300, their first cassette deck of the series. It had 3 motors, ferrite (glass) heads, and wood end plates. I really liked the option of operating it vertically or horizontally. I fell in love with it after seeing it on the wall at the late Pacific Stereo chain store here in California in the early 70's. This deck handled tape so well due to 3 motors. I would send it to the local Tandberg service center every 2 years for new belts , pinch roller, etc. Worked every time. It is in Brooks Berdan Ltd. Audio museum now after serving me very well.
