I am trying to build my own A1 module to repair my PH-01 phono stage.

I think those modules are encased in some sort of composite. Not sure if anyone ever successfully reverse engineered them.
However, PH7 internally looks very much like PH1 inside, so maybe that is an avenue.

Thank you for your comment.

As you pointed out, it seems that the PH-7 includes the PH-01.

I will also look into the PH-7 a bit.

Thank you for your advice.

We have received your comment.

I sent the message in English, but it seems to be sent in Japanese, perhaps because of Japanese browsers.

This text is also published in English.

After checking this result on this page, I am thinking of retrying with some other methods.

How about this time?

Thank you for your comment.

As you pointed out, PH-7 appears to contain PH-01.

I will also do some research on the PH-7.

Thank you for your advice.

The procedure went back and forth. I apologize.

Please take a look at the image.

I'm reluctant to reveal that I'm a moderate beginner, but here I will post the wiring diagram created from the image of the A2 board that Mr. Erikovsky obtained and completed.

Two of the resistance values written in red are unclear.
