power supply option

MIDIbox SID
1

Question 1-

Could i use these to power my SID and Core?

Question 2

If a can, would i use 2?

Question 3

What type of transformer (wall wort) would be reuired to power them?

Question 4

Could I use 1 wall wort to power both of them?

Question 5

Would there be any reason these power supplies would create ground loop noise?

I built the optimized PSU and it is noisy, granted i may have not constructed it correctly- I am looking for a power supply option that has pre-made circuit boards, so that it is not as messy, and hard to trouble shoot-

Thanks for any replies!!

Question 1-

Yes.

Question 2

If a can, would i use 2?

No. One running at SID voltage (with SID regulator bypassed) and regulator at the core regulating down to 5vdc (with small heatsink)

Question 3

What type of transformer (wall wort) would be reuired to power them?

Like they didn’t tell on that page?! 16VAC wallwart (or 16-18VDC wallwart..)

Question 4

Could I use 1 wall wort to power both of them?

Next question.

Question 5

Would there be any reason these power supplies would create ground loop noise?

It’s up to Your wiring. If you don’t create ground loops - there are no ground loops. Hah!

I built the optimized PSU and it is noisy, granted i may have not constructed it correctly- I am looking for a power supply option that has pre-made circuit boards, so that it is not as messy, and hard to trouble shoot-

And I would rather debug the optimized SID PSU, than build a new one. It should not be that noisy at all.

Thank you very much-

sorry for not paying attention to the input voltage part-

I think i will debug my optimized PSU first as you suggest-

FYI- I took my Optimized PSU apart today, and carefully rebuilt it on a breadboard-

It works fine, and is quiet-  Hooray-

Thank you for your help… and your patience!!!

Now to carefully build it on a PCB-

Ah, Great!

Sorry - I sounded a bit cranky..  :slight_smile:
