Luxman A-007 --- Schematic?
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?
(Note: this is my first post on this magnificent forum, pls apologized for my awkward English)
