3 terminal Jung Super Regulator Kit

The answer is 42 was mine. If you ever see me give a simple answer to a question I am most likely making fun.

Thunderstone:

>I find most 78XX/79XX (in fact all I tried) to sound very similar with a few 1,000uF after the Reg.<

I have conducted blind listening tests on 78xx/79xx regulators from various manufacturers, and in the test circuit applications, the regulators were frequently followed by a fair amount of capacitance. My experiments suggest that the statement quoted above may not necessarily be true for all circuit applications.

Yes, if you were reviewing loudspeakers 25 years ago. [/B][/QUOTE]

Haha, speakers are still the same KHorns......

I don't think he is bluffing since he designes some very eleborate discreet transistor regulators. Shown here with phono preamp, with carefully selected three terminal regulators. I have seen a closer up picture, its hard to see here.

>Topology is almost irrelevant, but PSU's bring big benefits to everything I've tried.<

Overall, I agree that putting more effort into the power supply usually yields subjective sonic benefits. Nonetheless, my findings so far suggest that circuit designs in which the total load current drawn from the power supply is constant - super shunt regulation, folded-cascode amplification etc. - the sonic effect of the PS filter capacitors is substantially reduced, and the sonic effect of the transformer is also reduced (albeit to a noticeably lesser degree).

Ooops, I was too overcome by the outpouring of information to give proper credit.

As for adding caps everywhere, did I mention I like to design boards to be small, diy or not, even if they are "only" low-tech linear supplies?

Sorry for the stupid question, but my experience is more in digital design, and not audio and DAC. And yes, my boards often use a decoupling cap on the digital supply, sometimes even more than one per board

(I will now go and rearrange my drawer of old neglected 78xx and 79xx parts in new and more esthetically pleasing patterns...)

[Bricolo]

aren't we supposed to only place low values caps after ICs regulators like 7805s,1085s,317s ?

I heard many times that <200uF is best, and that more isn't good, since those chips aren't designed for this

With a little digital masking....... a gentleman never tells.

And what do I conclude from that???
