Aleph 30 Help
 
Ok I need some help. I am using Perer Daniel's a30 boards. First my ps is +/- 31vdc under load. I am not sure if this is my problem or not. When I start it up I get +31vdc on R14, -31vdc on R39 and +30vdc on R27. I have no idea how I managed that. Any ideas would be a big help.

If you are building an Aleph30 for 30watts at 8ohms, the rail voltage should be 25vdc. You might consider adding more resistance if you are using a CRC arraignment in the PSU.

Here's a link to the PSU simulation I used and it worked out well.
