A few words about National's flagships Jump Cassette Players

The Jump RX-SA200 and his little brother RQ-JA100 (1986) are National's pinnacle cassette players sold exclusively in Japan. They are unique compared to other National players, mainly because they were built as sleek and fashionable, attractive players with sophistication in mind. This achievement reflects the rivalry between the National (Panasonic) and Sony brands.

These two models are a follow-up to National's RX-S40 (1984) telescopic slide concept pioneered by Sony's WM20/10 in 1983. However, these two Hi-End Jump models are the first players to use a unique flat battery. And an amorphous head that was relatively small to reduce excess space. These players are superior to the Sony WM20/10, WM30, and even the updated WM101/WM-F101 in many areas, such as power output, size & weight, and sophistication.

The RQ-JA100 is a plain cassette player. The RX-SA200 is a cassette player with a tuner. They are very efficient in power consumption and play even longer; with 4 hours of speed-charging time, you will get 5.5 hours of use. You will get even more time combined with the battery pack and battery adapter for 14 hours of listening enjoyment.

Intelligent and sophistication

National did put a lot of thought into those players to be as perfect and intelligent as possible. For example, the slide-out cassette compartment (see bottom picture) has a lock that pops up whenever you want to insert a cassette. Doing so hides the projecting parts and controls from accidental damage unless you close the door compartment; it won't engage. Also, the open/eject switch will stop and eject the cassette simultaneously for a quick cassette change. Other highlights are that the head is housed in a metal frame to protect its azimuth alignment, and the head housing also serves as a tape guide. Moreover, the azimuth screw is always visible even if the cassette door is locked.

More Sophistication

Besides those hardware features, there are a few electronic features. For example, to prevent battery drainage, you'll need to plug in the earphones for the players to work. Also, the RX-SA200 radio will not work if you switch to the radio unless you will also press play on the tape transport.

3-Way power supply

The Jump players have three power supply methods. Besides the flat rechargeable battery, you can use them with three alkaline batteries. Also, the RP-BA101 battery adapter can add more power. It houses the batteries and even has a place to keep the earphones. And, of course, you can always use the AC adapter/charger.

The Big Conclusion

The year is 1986, and National presented very cool new players to their lineup that, without a doubt, left the competition overwhelmed, not to mention the Japanese design award they had won for these two eye candies. The Jump flagships are impressive, with a full metal jacket and excellent build. However, these players have one downside. To make them as light as possible, National used a thin metal jacket that can easily bend with medium pressure, making them fragile. Now, fast-forwarding to 2022, these are very cool players who stand the test of time with quality build and excellent sound; they are THE wet dream of every collector. Unfortunately, not everyone can get ahold of such exclusive and exquisite players. As I've mentioned earlier, they've been sold exclusively in Japan; even in Japan, they are very scarce, making it even harder to obtain one, even though it is well worth it; if I were you, I would get one to just to brag it in my collection. However, if you're going to obtain one, be prepared to shell out a considerable fortune because other collectors want it as badly as you do. So good luck, because you're probably going to need it. Please feel free to comment.
