Thanx a lot!
The posted ad from Bulgaria is actually mine. If I do not find the schematic, I am considering selling it as it is, stating the problems.
Hope someone can share this schematic.

Mr. Anders Thule can't help. I was offered to perform a repair of the power amp section, but to create a schematic I would like to have at least three devices of the IA120 for service.Ok, why don't you contact Anders Thule directly? He's on Linkedin and now works at Oticon.
Most probably, he may still have them - or know someone who may.
Cheers,

Otherwise the effort for the schematic creating (reverse engineering) is not worthwhile.
Well Tiefbass, I guess there is one thing can be said about you - you don't give up easily, do you? This thread is now almost 10 years old!
You may now have to perform a "blind" repair, ie. without a schematic.
It is possible - and it separates the men from the boys.
But yes, it takes quite a bit longer and at some point you will have to ask yourself - is it really worth the time and effort? I mean, Thule's amp designs were good - but are they still "high-end" in today's world?
In any case, all e-lytes are probably old, dry and degraded 85oC types, the transistors have probably lost quite a bit of hFE, contacts and solder joints would be oxidised, etc.
But hey, you really must love this amp - so go for it!
I can't help you with a schematic, but if you get stuck do send me a message and I'll readily give my best advice.
Cheers,

Now I have 3 pcs. of this integrated amp devices. If I have at least 5 or 6 pcs, I will create a schematic with help of the disassembled main board.
Who know, how many pieces of this model was manufactured and where are test reviews ?

From the IA70 (same design than IA-120) I don't find informations on the web. I think, this model is still more rare than IA-120. Also schematic wanted.
I bought these two from hifigenbrug.dk and the nice gentleman told me that IA70 was the first amplifier Anders Thule/Thule Audio ever made. And only 250 of the IA70 have been made. Fun fact if it's true.. I haven't been able to find any info or pictures of IA70 until I found this thread.

yes - go to post #5 under
HIFI4ALL Forum: Thule IA100 Årgang?
who can upload the there mentioned test report ?
I think, it wasn't this magazine:
HIGH FIDELITY - Consumer audio and music magazine
there are also users in Denmark looking for schematic
