Service Manual for Sansui AU alpha 607DR?

[SansuiJavier]

Hi everyone, I have gotten a precious alpha 607, and the truth is that the sound is fantastic, the best I've heard so far, inside Elna Silmic, but also a lot of nicotine.
I have searched on HifiEngine and can not find the service manual.
Can someone tell me what equivalent manual I can check? Could it be the 607MRX?

Thanks in advance,

Congrats - a lovely amp!!

The AU-X711/AU-X911DG has the closest amp board circuit design, but I couldn't say for sure which of the service manuals should be followed regarding setting the bias current.

Pete is right. It looks a hell like a 911dg. And 911dg looks a hell like 711. I don't think they have any bias difference 711-911. Now DR was a successor so I don't really know if it does indeed have the same bias.
Beautiful amp.
