All current orders have shipped out. I currently have LM3886 kits/pcbs in stock, along with the PSU boards (both large ones and the small snubberized ones).
Current Specials:
LM3886 stereo kit: $50
LM3886 dual mono pcb: $15
Sorry for the recent delays, as I had some parts ordering delays, and have also been very busy with my job. I will try my best to be quicker on handling orders. I have LM3886 and PSU kits prepared and ready to ship out.
As for the LM3875 and LM4780 products, I am currently out of PCBs. If your 3875/4780 needs are immediate, Peter Daniel should have them in stock.

Re: BrianGT where is my order?
Yes, I shipped the order with you back around March 13th. I would have expected it to arrive by now. Could there be customs delays? The other orders that I have sent to Italy lately have arrived without issues.
Drop me an e-mail and we can figure out what is going on. I might have missed your earlier e-mail, as my mail server was acting up due to too strict of a spam filter. This has been corrected.

any issues with the 4780 board?
Hi, I've got a pair of Brain's LM4780 boards. I notice the schematic has Rz1 and Rz2, but they are not on the board??? where do they go? Also, do the R and C numbers from the schematic match the corresponding ##'s on the board? Hmmm.....In fact it looks like the outer sides of Cz1 and Cz2 (on the board) do not connect to anything at all (no traces)?
I'm sure there is a thread here but after 45 min I cannot find it.
In addition there are some unlabeled pads on the back of the board, what are those for?

Re: any issues with the 4780 board?
I am sorry for the confusion. Here is how the resistors mount on the back of the board:
Let me know if you have any more questions,

An externally hosted image should be here but it was not working when we last tested it.

great
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?

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.
