squalle 0 Report post Posted February 16, 2006 btw, I've managed to get my MOSFET-based power stage up and running and I just received 2 more tubes, GE 5963 and GE 5814 currently rolling the 5 different tubes i have Share this post Link to post Share on other sites
huangyong 0 Report post Posted February 17, 2006 squalle , how's ur mosfet stage? good? and i concern bout the heat, how big is your heatsink? Share this post Link to post Share on other sites
squalle 0 Report post Posted February 17, 2006 heatsinks (for mosfets and LM317 CCS) are big and heavy. heavy enuff that I wasnt careful last time that it broke my regulator's legs but hmm now all is well the mosfet stage doesnt change anything, which wat it supposed to be IMO oh to cool the whole thing down, I have this 80mm PC case fan blowing towards all the heatsinks total I have 4 big sinks, and 4 smaller ones for my PSU regulators Share this post Link to post Share on other sites
