Nakamishi TA-1 Service Manual

Hi all,

I am looking sine a long time (years) for ServiceManual or Schematics Diagrams for Nakamishi TA-1 Tuner/Amplifier to repair my power supply :

When I power-up the device, after a delay a a relay click, right channel is OK, but left channel only makes some low frequency random noise ...

Your help would be appreciated.

Best regards,
