  Try pulling the other electrolytic capacitors. If they were stressed they could be shorting internally. Maybe they weren't sealed good and some alcohol got in there. The output capacitors probably wouldn't have any effect though, if they shorted it wouldn't affect the power supply.http://www.elna-america.com/tech_al_reliability.php

  Are you sure it's the adjustable version? Or maybe R31/R32 are swapped. Can you take a picture of it?

  Did you install R31/R32? Pins 1/2 are the output pins. Pin 4 is ground. Are you numbering the pins correctly? 5-8 all on one side are tied together and connected to the input voltage.

  WOW! I can't believe you managed to etch that double sided at home. That's awesome.

  http://www.head-fi.org/forums/showpo...&postcount=169 I don't know how a different value would affect it though. I suspect using lower values would be worse.

What is this?

A prototype service to index some of the most interesting huge threads on Head-Fi. Once development is complete, we plan on asking the Head-Fi maintainer if he wants to integrate it in the main forums.
