Datasheet psu, 0.1v to 50v @1a...
 
HERE :magnify: :

...My question is, what would come between this regulator circuit, and the power transformer.......bridge and smoothing caps??

...And what :magnet: transformer say you?

You'll need 35-40 VAC, 70-100 VA, 2200-4700 uF in smoothing.

I friend of mine built this PS long time ago and it worked pretty well.

Thanks peranders.

...btw, how could this be turned into a dual polarity supply?
...or is that a drasticly different circuit altogether ?

You can built two identical PS and then connect them in series. This will give you a dual suuply.

I'm sorry, I meant a bipolar psu....."plus, minus ( and ground, 0v)" volts output.

peranders 22nd April 2006 09:14 PM

I ment that too. :)

redrabbit 26th April 2006 01:32 AM

OK, so using a center tapped tranny....
positive is one psu,
negative is another,
....and 0v (ground) is shared with both.

Correct?? ( :xfingers: )
