The common rule with all those Personal Stereos is their State-of-the-Art; High-Quality Sound, Excellent build and Unique design - in other words, Personal Hi-Fidelity Analog music players for the soulful man. The main interest (but not limited to) in Walkmans is AIWA Personal Stereos from their early years' product line from 1984 to 1991. The main interest in Minidiscs (but not limited to) is Sharp Minidiscs. I will post pictures of rare Walkmans and Minidiscs with information. Thank God for making all this possible, I hope you all will enjoy my blog.

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 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 adaptor for 14 hours of listening enjoyment.

Intelligent and sophistication

National Jump RX-SA200 & RQ-JA100 Amorphous Head
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 adaptor 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.

ÅNGROM DU - Hi-Fi Deposition Tape for music

2) High noise accompanying tapes are significantly reduced, and the lingering sound is beautifully reproduced. 46 DU 70μs EQ Metal - Standard Price 1,400 Yen.

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 built. 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 built and excellent sound; they are THE wet dream of every collector. Unfortunately, not everyone can get a hold 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 acquire one, even though it is well worth it; if I were you, I would get one to praise it in my collection. However, If you're going to get one, be prepared to shill a considerable fortune because other collectors want it as bad as you do. So good luck, cause you're probably going to need it. Please feel free to comment.
