Hi everyone,
I'm looking for schematic diagram of AG6747_3, or the value of R38 for the above PCB.
The symptoms,us I checked previous topics, are well known common issues, us no signal throughout main outputs(only PFL works).
So far I found U2 and R 38 damaged.
Any help welcome and appreciated.

Problem solved!!!
Replaced U2 with TL072 SMD and R38 with 10ohm/0.5W.
Currently all works.
Thanks to everyone!!!

Alternatively PCB AG6747_3 could be ordered in UK,from AUDIO-TECHNICA for £23.
Part number 003#656


Cheers

Do you have any idea where I can order that board AG6747_3? I looked on Audio Technica in UK and I can't find it. I need that board for my zed 18! Any help would be greatly appreciated. Thanks.

Dear Vasilgv11,
Can you tell me, where you ordered, that PCB? Unfortunately, I am not able to find it on the Audio Technica site. If you can share with us the schematic diagram, that would be highly appreciated. In AG6747_3 the U5 and two other resistors went off, but unfortunately, I cannot see it in the board as it is a bit burnt.
