Service manual for Sony TA-E90ES available here

Or you could try www.sharefx.com. It's free, though it requires you to sign up before you can download.
Once you signed up, you make a request, and if anybody has the SM, they will upload.

Best regards

Dear,

I have the service manual of the Sony TA-E90Es pre. Send a email to bas_music@yahoo.com if you want a copy 😉

Great pre-amp btw.. and highly underestimated in the world of audio. I like the TA-E90's discrete voltage regulators. With some down to earth mod's you can turn it into a great pre-amp.

Best regards,
Bas

Any suggestions on mods for this unit? I am thinking of doing something with the coupling caps (C409 and C459, i believe). Any other suggestions?
