"still no sound through the guitar input but it’s louder through the CD input:
The CD input goes directly to IC4 pin 6& then to the output ic, TDA2050.
So if that works and the Guitar input does not then your problem lies between the input jack and IC4 pin 6.![Frown](https://music-electronics-forum.com/core/images/smilies/frown.png)
You need to trace the signal through the preamp to see where it drops out.
