srecenvid

Thanks audioguru. I have 500 and 1000VA transformer 24V in my small lab and i can try to do also 10A version. About heat and transistors i have really big cooler with water cooling, so that wont be problem probably, now i have only found enough big resistor for this...will check tomorrow my inventory and see what i have. about driver transistor i was thinking maybe i can try and use 2 drive transistors and opams, but that will change scheme alot? or is that stupid thinking? or you maybe help me find enough big opamp and driver transistor... anyway good night, i am ready for experiment :), will check all needed parts tomorrow and see if it is even possible :)

hey. yeah it was mistake XD actualy i thought its also 30V power transformer. anyway it was not much wrong, only one mc34071 was blown up and 10A trimpot+potentiometer. after changing this enverything work great :). i am doing now also ammeter/voltmeter lcd panel... do i post some pictures or project files? thanks for help. u know maybe if someone tried to do 10A version? or does it need other power transformer (toroidal transformer)?

hey. i have a problem. i built now 5A power supply, it was working great, until i did not try today it with 48v power transformer. now i have constant 35v voltage, also cant adjust it. anyone have idea what can be wrong?

sorry but i CAN NOT attach any image or anything on this forum :( dont know why but i am getting every time when i try error. there is one more link there is 2400dpi picture :( http://dl.dropbox.com/u/18635567/pcb2%20%281%29.png

oh i see... ok there is full quality scheme. sorry one more time http://www.box.com/s/5co1y61jyyke8uc4utcz download it for full quality and thanks a lot for your help and time.

Hey. i made this scheme in eagle. i dont know if its ok, can someone download and check if everything is fine? its for 5A project. p.s. attachment doesnt work for me :(

why i cant see 118 page when i am logged in, but if i log off i see?

hey. Thanks for fast replay. My 3A supply is working perfect, now i will try 5A. i did scheme for 5a, as u said, can u check scheme and tell if everything is ok? thanks alot! P.S. sorry for 2 posts :( did not know which is more active

hello. i am new in forum. i checked yesterday almost all 118 pages and i have to admit that you are all amazing. Audioguru you are doing really good job. I already built today 3A version (will upload pictures after testing it). I found also picmaster's Schematic and i am interested to build 5A version also. Can u point me where to find picmaster posts and part list. is there any forum where can i read about 5A project? thanks alot for answers
