Blues 0 Report post Posted July 5, 2003 Next meet? No.... I'm taking my time to build the amp. It'd be at least 2 months before I even finish the supply. good luck firefox!! remember if you r going to let anyone audition it call me first kekee Share this post Link to post Share on other sites
jasonhanjk 0 Report post Posted July 6, 2003 Hmmm... Output voltage set to 23.90 to 24.00 V. It has capability to set to +-15V if an upgrade is required. I am thinking adding a fan inside so that it will maintain at this voltage for a very long time (slow component aging)... Let's test on CLONE PPA, hope it don't blow infront of my face...

Fans then to throw out a fair bit of EMI.. So it might not be a good idea to do so. Share this post Link to post Share on other sites
jasonhanjk 0 Report post Posted July 7, 2003 The transformer sucks, heat increase my resistance hence reduce output voltage. Going to get more heatsing and see whether does it improve... This teach me a lesson on my first DIY power supply unit... Share this post Link to post Share on other sites

This teach me a lesson on my first DIY power supply unit... I curious as to why the heat problem and voltage fluctuation. The PPA shouldn't draw too much current, maybe I'm wrong. A few of questions, What is heating up? The transformer or the Voltage regulator? What's the secondary voltage of your transformer? Share this post Link to post Share on other sites
jasonhanjk 0 Report post Posted July 8, 2003 (edited) Hmm... I think I know why. I need to devide my 2 secondary winding, must be very careful.... It comes with 2 secondary winding solder together... Edited July 9, 2003 by jasonhanjk Share this post Link to post Share on other sites
