Hey Guys,
I recently bought a JDS Labs CmoyBB for my sister and she loves it. She's a IT Professional and spends most of her time at the computer. Since she does not need portabilit, I have been searching for a power supply for her Cmoy. After many hours spent it looks like I will have to build the power supply because sourcing one with a reasonable price seems impossible.
Big thanks to Tangentsoft, his website has proved to be an invaluable resource in this undertaking. I have spent several hours reading through his articles/guides and that has, well, given me courage to try this.
As he mentioned the LM7824 to be a good choice for this purpose, I have been looking for a schematic simple enough for me to execute with high chance of success, and I have settled on this: http://www.circuitdiagram.org/24v-dc-power-supply-using-lm7824.html
To save time and money I plan on only building the regulating circuit, stick it into an enclosure, and put it between this: http://www.lelong.com.my/24v-1a-switching-power-supply-adapter-100-240v-ipstore-F41244-2007-01-Sale-I.htm and the Cmoy. (that power supply listing is RM20 which is less than 6 USD) (I reside in Malaysia, therefore the 220v UK plug).
One of the important requirements Tangent talks about when it comes to power supplies is "Isolation". However I'm not clear how to incorporate that into the circuit. What changes should I make to ensure Isolation?
Right now this project is completely in the planning stage, and as such, I am fully open to Suggestions and Recommendations. It would also be really helpful to get circuit ideas from those of you who have built a linear regulated power supply for a Cmoy or similar amp and has had good results.
Looking forward to hearing from you guys.
