Various parts have been maintained, such as capacitor replacement and solder repairs, etc., and the sound quality is exciting and unimaginable from its small expression. It is a compact all-silicon transistor power amplifier developed in pursuit of sound transparency. You can see a feeling of use, such as appearance, dullness, abrasions, etc. (Kobayashi Hitoshi)
Maintenance information: 2025.4.9 maintenance completed (LR volume replacement, power boomp circuit, electrolytic capacitor, film capacitor replacement, solder repair, internal inspection, cleaning, running test, etc., each switch is slightly eccentric, but there is no functional problem ※ since there is no relay circuit, there is a slight popping sound when the power is turned on)
Accessories: none
