Can a 5V / 9V C64 psu power 6581 SIDs?

MIDIbox SID
1

I bought everything i need (at least i hope so), and i noticed that the PSU reads:

“Output: 5V - 1.7A    9V~1A    18VA”

But it is known that the 6581 needs 12V instead of 9V (8085) :-\

I have two 6581 i’m gonna use for a stereo setup. Will this psu work???

I will be really pissed if i have to buy another one  ???

Hi ytsestef

thats ok, just look here: http://www.ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf or here http://www.ucapps.de/mbhp/mbhp_4xsid_c64_psu_optimized.pdf or here http://www.ucapps.de/mbhp/mbhp_sid_c64_psu.pdf. I think you can figure out what is what depending on its name.

hope i helped you

Thanks a lot for your reassuring answer, i was worried that i needed another psu.

However, the schematic for the optimizing circuit seems a bit complicated for a noob like me with the 2 switches meaning different pins of one switch (i guess), and the 2 pins of 5V DC (is one of them ground?), and the power led socket which i don’t need and don’t know how to remove…  :cry:
