I sent my cd player to a friend's house two days ago. He mod the TLO71 with the OPA627 today.
A socket was used so that I can try different op amp later.
He also re-soldered the wire at the RCA joints as it seems like not properly joint.
The player spin. All is well BUT:
According to him, there is a high pitch sound at quiet passage. He put back the TLO71 but the pitch is still there. I have not heard from the player after the mod and I do not know how bad it is. What could be wrong?
