I downloaded to check, and that is what I got, but I'm going to update it to add page numbers. I think yours is stale, but I can't figure out how/why.

Right after I posted, I downloaded from the website and found it to be correct. I saved it over my stale local copy so now I can't post what I was looking at. The problem was that the bypass caps were oriented vertically on the drawing and were in series with the VCC not across VCC and GND.

Look into it later when the dust is clearing off the crater.

Thanks to the modern miracle of system backups - lol - here is what I was looking at.

I had a small issue the 3k resistors in the anode part of the build.
Namely that I put them where the 1k's shoudl have been. I pulled them off and installed the 1k's where thye were meant to go, however the 3k's are a little worse for wear after being removed from the board.

My local shop only has 0.5W MTL 3K0 1%. They are 3k, however have a different tolerance than the supplied ones. Will these work in their place?

Cheers,

They'll be fine if they fit.
