Super Regulator
As I see it both polarity super regs are connected in reverse polarity. Your center tap/GND should go to the outside contacts of J1/J5 according to the silk screen picture in diyaudio store.

Regards,
Oleg

That's what I thought, too! Figure 1, in instructions is misleading.
This is the correct way to connect with a pre-regulator. The ground is on outside of J1 and J5. correct?

Now how to troubleshoot?
I am measuring
19.8v on positive reg.
-9.18v on negative reg

When turning on:
positive reg LED turns on shortly and goes off.
negative reg LED stays on.

Target output is +/-17v

Fig 1 is the circuit diagram, NOT a physical connection diagram!

Fig 2, the physical connection diagram, is correct as far as I can see.

Yes, now I know
D2 is dead. What other parts should I replace?

No. D2 and D7 tests good. What part will likely fail if input polarity is reversed?

What supply voltages are the two super-regs expecting.
Splitting a +V, 0, -V dual polarity as you have shown, does not look right.

Expecting +/-21v, which is what I'm getting from the pre regulator. I have another pre regulator with separate output grounds. At this point just trying to figure out which parts are likely fried after connecting the Superreg backwards.

@Jan, not very natural to have the ground and Vin swapped. Why? It's very easy to make the mistake above.

@navigera, the opamp is most likely fried.

PA,

It's been years since I layed-out that PCB and don't remember why it came out the way it did. For some reason the result was better or I wouldn't have done it.

But surely you wouldn't put parts on the board from their position on the schematic either?

Jan

I've made the conscious decision to include protection against reverse polarity input, on all of the PCBs whose Gerber CAD files I give away here on diyAudio. I figure it's cheap insurance and the loss of headroom is tiny when you make D1 a Schottky type.

D2 might be gilding the lily a little. It's a 2nd safety net in case two bad things happen simultaneously: (a) the user connects the input voltage backwards; (b) D1's reverse leakage current is enormous. Then D2 clamps the negative voltage on |Vcc| to something less than a silicon diode drop.
