What about the inside? Transformers are mainly made by Hashimoto Electric depending on the specifications, and Astro Denshi's custom-made transformers are used for the high-end models.
For example, the self-bias capacitor is 8,000 microns, which is much larger than the 200 to 300 microns generally used.
This ensures that even at low volumes, the sound is expressed well without sound loss. These parts are carefully wired one by one with a single oxygen-free copper wire.
The circuits are wired in a two-stage structure with heat dissipation, vibration control, and noise suppression measures. Astro Denshi Kikaku's wiring is beautiful without any disorder.
It is a construction that gives a sense of the realm where a craftsman has reached.
The chassis is supported by a foot base machined from an oxygen-free copper and aluminum alloy block. Young cowhide leather is inserted between the foot base and the chassis for further vibration control.
In fact, Astro Denshi Kikaku amplifiers are equipped with a circuit breaker that can be detected from the outside, and a blue (or green) LED amplifier lights up under the body if there is any abnormality.
This makes it easy to determine whether the problem is caused by the amplifier or an external factor, so it is an unexpectedly useful feature in times of emergency.
Closing out the amplifiers are the anodized 10mm-thick aluminum alloy front panel and knobs made of aluminum alloy blocks.
The slippery feel is very pleasant and easy to handle.
This time, we mainly introduced the high-grade amp with stainless steel body, but the amp with a less expensive aluminum alloy chassis is basically made in the same way.
The aluminum alloy, commonly known as 52S, is rust-proof, high-strength, and especially strong anti-fatigue.
How was it? I hope you now have a better understanding of Astro Denshi Kikaku's products. Of course, the most important thing is the sound!
In a word, it is "highly transparent. It's a straight and pleasant sound with no coloration.
If you look at the price alone, it is a bit expensive, but considering the contents and production process, I think it is not expensive at all.
