Miracle! Fully restored! Superb, fully functional, ultra-beautiful item with original box! This is a LUXMAN pre-main amplifier L-504. The exterior is very clean (repainted) and maintains a shine like new. I don't think you'll find such a superb item very often. Also, in terms of operation, there is no scratchiness in the switches, and the sound, which is characteristic of LAXMAN, with its power and spaciousness, comes out evenly from left to right. The restoration includes replacement of defective parts, contact cleaning of switches and volume controls, reinforcement of solder joints in key areas, circuit inspection using an oscilloscope and tester, cabinet painting, etc. If you are looking for a superb LUXMAN, please consider purchasing it.
