Hello there!

I got an Luna 2 card as a gift. The card is may defective. I noticed, that the power regulator LM1086 got some mods in the past. There are some SMD resistors or capacitors soldering in between the pins. Is it an official mod or something else? May someone know something about it?



Cheers, Andreas

I put the card in my backup PC. It works. I just had some hassle importing the keyfile. It first seems not to be imported by the SFP4.5 installation. I had to start SPF after "failed" installation and found the keys imported. May that has nothing to do with the mod on LM1086 - but anyhow it works.

my luna doesnt have this mod. you can find the schematics for the regulator here:

i believe whoever used this mod didnt have the original regulator and had to adjust the output voltage with the 2 resistors
