Hello does anybody have the datasheet of a TA7135? Or can anybody tell me the difference between the TA7135 and the TA7136? Because in the schematic of the Boss CE-1 I see written that IC1 and IC2 is a TA7135 but I have a CE-1 for repair and here it is a TA7136!?!

The schematic that I have seen shows IC1 and IC3 being TA7136P, and IC2 is MN3002

You are right about IC1 and IC3. But I saw these schematic. https://www.pdf-archive.com/2017/11/21/ ... rretboard/
And here the note on the left refers to IC1 and IC2. Probarly this is wrong. Also the type IC is written as TA7135. But I cant find a Manual of these IC. Perhaps its also wrong?!
But in one of the schematic in your link, its not a TA7136 but a TA7504S? What about that?

When able, always use the factory schematic!

And now I'm sure that within time someone will show up stating that there's manufacturers that deliberately put errors in their schems. If so, please show me one with the proof that the error was put in there intended.
Sorry. Plain out of planes.
