Hi,
amazing news -> Analyzer is working !
I changed the resistor to a diy fused one (-;  With low melt solder it should open if the resistor gets red hot. I hope not.
There are two new 100nF 630V capacitors as a replacement soldered on.

At the first start the analyzer found no HDD and the BIOS stopped. At the second try and several times later it was no problem, the analyzer was booting well. Date and time was all right. BIOS Battery seems to be still ok. Next step is to clone the HDD for backup and clean / lubricate all the fans. Some sound a bit rough / noisy.

Thank you for the support!
