[5 x LM338K]

Dear Shahriar

To me appears this reason that you say. Simply I have already a regulated power supply 20A, and I wanted to make a half simpler, without transistor, pcb  and the rests. I do not know him I will think. In any case you I thank too much.  :)

My english is...not good :-\ sorry.

[5 x LM338K]

Thank's Audioguru ;)

[5 x LM338K]

If I put 5 x LM338K (5A) parallel (like the circuit), I will have 25A power supply ??.

[Help for power supply.]

Hi again :D

You can forget about the 0 – 30 Volts @ 20A for this circuit (as Audioguru already told you)!

Ok but where is the wrong into the circuit ?  I don't understant the fault :-\

[Help for power supply.]

  I dont understant ... the circuit work very well ... (with fans).

you must add an adjustable current regulator circuit to it.

Yes but , I don't know the circuit.  Can you help me ?.

Hi moutoulos,

Before this circuit was changed (from the original by WA0AUQ), it had a 18Volt transformer and it was intended for a fixed 13.8V output. It would work fine this way!
This is the original:

:o So .... I agree with you, (edit from me),  but you don't answer in my questions,  and this is the point. :-\
I don't have any problem with power supply ... it work two hours every day (test car amplifiers...13V) the last two years.
Well  :'( 0-20A??

[Help for power supply.]

I have this power supply (0-30VDC  20A) and I would like someone to tell me If I can convert it to 0-20A.  And how ???  :-[  please.
I test sometimes small pcb, and if they are wrong... it burned (pcb)  >:(

I want your opinion for the Velleman Kits. I mean if him you have worked... and generally if they deserve they are characterized "quality kit".  :)

[Convert 0-30V 3A PSU to 5A or more]

;D ;D

tnks audioguru

[Convert 0-30V 3A PSU to 5A or more]

Finally... with 3 2N3055 how is the max current??

I want put 4 2N3772 can I?? If yes how is the max current??
