Hi KatieandDad,

I measured all the components on both amps. They both measured OK so I got confused. I was expecting to find defective transistors at least. But all seems to be ok using the diode test..... I'm not saying that this test is 100% conclusive, but both the left and right amp measure exactly the same on all components.

So I browsed the internet and found this:

How to Measure DC Offset: 5 steps - wikiHow

Don't know for sure yet, but it would explain the shabby sound on only one channel. My speaker protection unit could have been cutting off the left amp while stil running the right amp. But if the DC offset is very high, that could result in crackling sound couln't it?

I'll try the methode described in that article tomorrow :-) I'll let you know how it turnes out.

Kind regards,
Sjoerd Smits

Didn't know what you were trying to say with C or CRC.... :-)
Thanks!
Yes I realized that once Katie and Dad nailed it down Easy to forget sometimes that some of the stuff we now take for granted we would have said "whats a CRC" ourselves when starting out!

Hi Tony,

You are so right! But hey, I'm a guy and I'm supposed to be cocky offcourse :-)

I was so confused that I didn't "see" your question the way it was intended. I apologize for that!

Thanks for the lesson :-)

Regards,
Sjoerd

PS: Tonight I'll set the DC offset while connected to an empty input... Hope to get better results!

Thanks again all!
