Japanese precision from the late 70s. The RS-M33G represents Technics at their peak — when Matsushita wasn’t just making gear, they were engineering it to last.

The vintage advantage:
This is the G variant — the glassless cassette door model, which is harder to find than the standard version. Technics used their digital FG servo motor for rock-solid tape speed, which means you get consistent playback without the drift that plagued cheaper decks. The SX sendust heads were specifically designed for durability and performance — they last longer and track better than conventional ferrite heads.
The below service was carried out to get it to perform within original specs:
- Replacement of Capstan Belt
- Lubrication of moving parts
- Cleaning of heads and capstan with chemical
- Demgagnetisation of heads
- Speed calibration
- Playback level calibration
- Full function test
We provide 6 months warranty for cassette decks.
