experimental Posted March 26, 2006 Report Posted March 26, 2006 Question 1-Could i use these to power my SID and Core?http://www.circuitspecialists.com/prod.itml/icOid/2072Question 2If a can, would i use 2?Question 3What type of transformer (wall wort) would be reuired to power them?Question 4Could I use 1 wall wort to power both of them?Question 5Would 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!!

moebius Posted March 27, 2006 Report Posted March 27, 2006 Question 1-Could i use these to power my SID and Core?Yes.Question 2If 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 3What 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 4Could I use 1 wall wort to power both of them?Next question.Question 5Would 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.Moebius Quote
experimental Posted March 27, 2006 Author Report Posted March 27, 2006 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- Quote
experimental Posted March 28, 2006 Author Report Posted March 28, 2006 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- Quote
moebius Posted March 28, 2006 Report Posted March 28, 2006 Ah, Great!Sorry - I sounded a bit cranky.. :)Moebius Quote
