    Has anyone actually made any? what you think? I need 30v, 15v and 12v for a psu Im gonna make.

    I use a few ALW super regs to power a few components in my Hi-Fi.
    They work excellent for me
    Andy may still sell the kits if your interested

    Made a couple of Per's S&M regs & they are very worthwhile but can't compare to Andy's version unfortunately.

    Are there any regs out there that can provide enough current etc for a power amp?

    Andy's pcb is very well done and I can really recommend it. My pcb is a bit different, is smaller and has more features but basicly the same thing. Andy's design is very true to the original created by Walt Jung but I have changed some things.

    If you of some reason want stabilized PS for your power amp (very unusual!) I see no theoretical problems to blow up the design to be able to handle more current but don't underestimate potential problems because the design and the pcb layout is more complicated than it looks like.

    Thousands of regulators have been built. Last group buy at diyaudio.com ended up in 435 pcb's and my SMD regulator generated 61 pcb's.

    Good idea, a higher current diy super regulator would be excellent especially for the new T-amps etc
    Would it be possible to fit something like an LM338 to the SR to up the current?

    It's possible but it is unkown how much this type of regulator is getting along with a class D amp.

    This is a very valid point, how close to the the caps? where will you site the reg?, will low esr caps in close proximity screw the sound in this case?
    Mixed results I feel maybe>>>>

    Thanks Peranders:)

    Some good close up shots, have you tried these regs?
    It seems to use AD797,ADR421 and a irl3502 mosfet.
    So IT is sort of based on a jung regulator

    If you read the thread over at the other forum you'll see that I have had one of those regulators in my hand.... the picture have I taken also.

    If you don't look at the price, this is a very well done regulator with a very nice looking pcb, notice the goldplated holes and pads!

    It's very neat but what a marketing BS. What about this:
    "propriety self noise cancelling system" is a simple lowpass filter, resistor and a cap. You'll have to be a real poet to come up with such.

    I agree its interesting to see what's behind the marketing words:)
    So is there anything diy thats as good as these invisus regs which is suitable for an amp;)
    I want something as good as ALW's SR's but with a higher current

    I'll suspect that there are no power regulators in the super regulator leauge. Personally I think it's better to feed the driver of the power amp with good voltage and let the output stage have unstabilized power. As I said earlier I think it's possible to increase the output current but this requires some design efforts.

    I wouldn't connect the regulators in parallel but it's possible it works.

    I'm sure I have seen a 2.5amp unit some where, the digital sections of a few Wadia like a bit a current than most. Some even take 1200 ma (lots of dsp's & large cylindrical heat sinks) The super regs usually can't handle much more than 500-700 ma for long periods (even with a transistor change).So we had to come up with some to cope with this.
    They are such units about, though I feel they initially weren't designed for Audio.
    I would agree with Per on the main supply voltage feed to amp though, good results can obtained that way.

    A super regulator can handle several amperes without problem. I have tested my JSR03 with 1.2 A, 25 volts out with good results and this is the basic design. I see no problem to get 10 A out with only little degradation of performance.

    This very minute I have uploaded my new future project. I'll expect to make pcb's in a couple of months.

    It's a super regulator with 115/230 volts in and +- 15 volts out. Expected output current 200-300 mA.

    I can be found here.

    Picture here.

    Thank you Per, though I have to say none so far have survived the wadia digital section test LOL

    In what way? 1.2 A which I tested requires proper cooling.

    Yes Per, serious 3.8w/deg heat sinks plus vents they just can't seem to handle it, no thermal shut down as its a transistor not a regulator i/c, they just go belly up lol
    The unit now will handle 1.8/2 amps constant and 2.5 A at peak. so Its all running tickyboo now and no carbon smells hehe
