Luxman A-007 --- Schematic?
Dear All;
I just get Luxman A-007 Direct Digital Amplifier, given for free from my friend because it didn't work anymore. The problems are from dead switching ICs... so I replace both TC9163N --- and now it work find  Also, I replace all opamps: 3xJRC4580 + 1xNJM4558 on Preamp Module 1xJRC4580 on Tone Control Module 2xJRC4580 on DAC Module all replaced by LM4562...... now sound more transparant/impactfull then before. I'm just curious, did anyone have complete "schematic/service manual" for this unit? Thank you. (Note: this is my first post on this magnificent forum, pls apologized for my awkward English) |
