Special ordered model

Reliable manufacturer maintenance

ASTOR middle class integrated amplifier.
It firmly inherits the flow of ASTOR's amplifier, which has a high level of transparency with no decoration.
It has been overhauled by the manufacturer. The warranty period is as long as 5 years, so you can rest assured. (Vacuum tube is guaranteed for half a year)
The full-body luster and the black body are also cool.This AS-6550PM is an amplifier ordered as a special specification by the previous owner.The capacitance of the condenser and the resistance were changed so that the large DAITONE speaker of nearly 50 years ago could sound sufficiently, and the vocal system in the mid-high range was expanded.By adjusting the B power supply, the voltage is also changed, creating a heavy sound while extending the low range.
