OK, great. I see for the PS you have the other guide, but its not quite exactly the same as the boards. I've always been confused by the way the AC1 and AC2 are labeled on these boards but I think I've figured it out.

Is the attached image the correct way to hook up the diode board to the transformer? Note I've added polarity markings to the transformer and a not "____" to the lower AC1 and AC2? I suppose it does matter how the secondaries hook up, you just cannot randomly use any orientation for AC1 (one winding) and AC2 (the other) without paying attention to the polarity of the windings?

That power supply image is correct. The polarity labelled is correct. Sorry for the confusion and lack of documentation.

Hope this doesn't sound daft but which kit sounds best and will it beat my audiolab 8000a? Power is not really a concern, I don't listen that loud, although I am driving Epos ES14s.
Kind Regards

Hi Brian,

are you going to offer the A30 PSU boards again in the next future or do you have any left? I`m considering using them for an aktive speaker project`s amps.

Best regards

All current orders shipped out this morning. I have a few LM3886 kits left, and will be reordering pcbs for them soon.

Anyone knows why chipamp.com has been down for a week or more? Are they still in business?

Regards

Antonio,

The site has been down since last Thursday, and have been trying to get this straightened out. Apparently, he had server troubles, and moved to a new server. I am in the process of updating the DNS information for the new server, and the site should be back up in a day or two.

I was out of town on business last week, and didn't catch it until I was back home on Saturday.

Sorry for the issues, and everything should be back up and running ASAP.

Site is finally back up. It was due to my provider having service issues. I had to wait for him to get the files from the old backups, and transfer them to the new server. I had a misconfiguration for the new address in my DNS info for my domain name, so it took a couple days longer to get it back online.

I am catching up on e-mails now.

Once I am able to get ftp access to the site again, I will update the site.
