First of all, ty for this epic topic, i'm learning alot and mb will have a chance to save my s750 too.
Now here is my trouble:
I've the same typical meltdown aka flashing green light and brown glue of death. I tried to remove it painfully and regulary test it. Obviously I made a short circuit and both of my c40 blown out
Now I'm on my way to change all part Lex recommended but I've a doubt about this c40: Kukruse said It's a 100v cap but his reference links to a 50v cap (in parlist.doc)
I'm already extremely lost in the number of parts and nomenclature, I hope you can help me with this c40 (or an exhaustive list for the whole pack
but I can deal with research)Ty in avance

Hi, lex.
First af all, I am very thankful to you for this thread.
I have also a problem with my S750 set.
One day my S750 did not give the power at all. The main fuse was blown out. But I found also that on both amp.boards C40 were burned out totally - see picture.
Other components seems OK.
[attachmentid=3828560]
So because it was not clear why it happened, I decided to replace all components what were available at the Digi-Key.
Thus most of passive components were replaced - my BOM file is uploaded too. I did not test transistors/power ICs, but visually they were good.
At the final phase when I must to test my S750 I found that I lost my marks about how to connect amp. boards to the IO-board (the board with inputs/outputs) and to the power board.

Maybe somebody here can give me information about that.
