The RS-630USD is a front loading high fidelity cassette deck with large peak check meters manufactured in 1976 by the National Panasonic / Technics Corporation of Japan.
This cassette deck also had other versions as such as RS-630T and RS-630. This model was one of three in the series. There was also the RS-671USD, and RS-6766USD, which had advanced two motor systems. This series was specifically for studio quality sound providing the best sound reproduction.
It is not much to look at from the outside, and it does not have any of the modern-day distractions, but what it does have, is an HPF head that provides the same sound performance as new when out of the factory. For its time it was one of the most advanced models and in many ways still provides good recording performance. I recorded a couple of cassettes on this deck and listened to it on one of my vintage Walkmans and it sounded great.
Peak Check UV Meters
The illuminated 64 mm × 40 mm peak check meters look extremely smart, and they are very responsive with a smooth action.
It was a unique moment in history when two great Japanese names came together to build a fantastic product, and this vintage cassette deck has an HPF recording head, and a ferrite erase head, providing the ultimate in audio quality.
The output level from the headphone socket is fixed, and the sound is clear. After recording a cassette, I played it back on my Vintage Walkman, and the sound quality was impressive. It seems to be able to transfer bass and tone effortlessly.
The stereo microphone sockets work extremely well for recording live vocals. The microphone sensitivity is 0.25 mV when the impedance is between 600 Ω to 20 kΩ.
National Panasonic and Technics make some of the best consumer electronics products and if you ever get a chance to buy a quality vintage piece of equipment then I would highly recommend that you do so.
This lovely cassette deck came from the Matsushita facility in Osaka, Japan. Consequently, it has a value.
The top cover is actually metal, with a wood effect pattern. This is a large tape deck measuring 41 cm × 14.2 cm × 32.1 cm and weighing 7 kg. It is not a standard hi-fi size; however, you can keep it to one side in a pride of place.
Cost / eBay
In 1977, it cost a few hundred pounds, and was a mid-range product for professionals and semi-professionals.
Due to the HPF head, it is still highly sought after by audio enthusiasts, because the sound reproduction is one of the best in this old deck. Depending upon the auction day, and whether there are any audio enthusiasts, it can make a tidy sum.
