mbhp_4xsid_c64_psu_optimized question

Hello just a little question on the schematics:

is it like the other caps a 2200uF/16v or not? i don’t understand what mean 2200/25uF…

thnx by advance ;D

thats a typo, should be 25V

thnx to the one who update the pdf file!

Sorry for bumping this up, but i’ve gotta question to about this psu.

Is voltage regulator ALWAYS the 7809?? see mark 2 on schem.

So no difference if you use 8580’s or 6581’s???

Yes, always 7809.

This regulates 9V AC to DC, then adds this to 5V DC to make 14V DC.

The 14V DC then is used for either a 9V or a 12V regulator in the SID module.

Just finished soldering the bugger but nothing??? I must be doing something wrong. I use a double pole switch and only the 5V line lights my led. I think the problem lies by the BR. I have to check it again.

O yeah the C64 power plug on the schem is this the plug from the power supply or the one on the PCB???
