A peek inside Astro Electronic Planning's products reveals reasonably neatly wired circuits.
The sight of carefully selected components wired around a single oxygen-free copper wire is artistic.
The basic production method is the same for all models from the bottom to the high-end models. The same attitude toward reproducing the original sound is also the same.
The differences in price and grade come from the chassis material, shielding performance such as vibration isolation, and the price difference of each component used.
The folded mirror-finished stainless steel chassis used in the high-end models alone costs about 200,000 yen, depending on the model!
Most of the transformers used are made by Hashimoto Electric, but the advanced models use Astro Electronics' custom-made transformers.
Some models do not use Hashimoto transformers, but use transformers of the same performance as those made by Hashimoto Electric, designed by the company, to greatly reduce costs.
In this way, Mr. Kanesa, the representative of Astro Electronics, builds each unit one by one. Therefore, it is also possible to adjust the sound quality to the owner's preference.
This is one of the strengths of Astro Denshi Kikaku.
Mr. Kanesa is very busy for this weekend's vacuum tube audio show.
