English Amiga Board - View Single Post - Video and Audio Noise in Amiga 600 Rev 1.5

I have exactly the same problem.
Tried 3 different A600 Boards and everyone has that video Noise when,
the floppy is loading, the CF Card loading data like crazy,
or any CPU/memory related stuff.
Fact is that the 1.3 Board and two 1.5 Boards had all the same noise problem.
All of them are Recapped and i have 4 powersupply´s. From Original to Meanwell.
BUT, i found this.

Get this, he is exchanging the Sony CXA1145M to a Sony CXA2075M.
(in minute 9 of the linked video)
Very interesting and because the newer chip has some of the components inside (like the filtering) THIS is maybe the FIX i was always looking for.

What do you think about that guy´s?.
What are youre experience with the A600 Video output ?
