Hey Brian,

I know you've been super busy lately.  I was wondering if there was any progress on this project?  Even an official BOM for your board would be awesome.  I'm waiting on placing a small bear order for whatever I need but don't have for a dipthonizer and a forumvibe.

Thanks!

Dan

Actually, the prototype has been built, but there is a problem with it. I have not had time to track it down yet. I only finished it a couple of days ago and I'm in the process of reviewing my schematic re-draw to check for errors.

I can post the BOM here tomorrow.

OK thanks so much!  Sorry to hear you had some problems with the prototype.  Juansolo mentioned in the OP and I've also heard a few guys on BYOC say that the original layout has some errors.  That's why I stayed away from building this at first.  So if the schemo looks correct maybe looking at the thread on BYOC will help a little.  Good luck!

With mine there was a ground that wasn't connected where it should have been, and it needed a link on one of the board mounted sockets as the ones I sourced were the opposite way around to the ones the board was done for. Otherwise it was pretty much as the layout on the thread.

The biggest problems after that were making it fit in the enclosure with the through board pots (which were a little short, I'd do it different next time) and the fact that the sockets and 4 pos switch are backwards if you do it that way.

If anyone needs a UK source of genuine 3080Es, I got mine from Bowood Electronic. Comes in at £5.50 for two inc delivery.
