Minor update just to say thanks to all who have paid so far - printing, packing and prep is underway at present.
There are a few who have yet to pay, which is fine, after all it is only a few days since the requests went out.

Another update folks.
I have these ready to go out in the morning, many thanks to all who have supplied their information and paid. Once I have all the tracking numbers in the morning, I will email each of you with your tracking.
There are a couple who haven't either provided info or paid yet - given that there is a queue of a few others who would like boards, I think its fair to set a deadline for anyone to do both (unless by prior arrangement). So how about next Sunday night, 11th December?
@baggerpole, @kumori - check your paypal when you get a chance.

Stirling work Fran I'm sure it is very much appreciated by all. I'm shamed to say my attempt to help the GB with some of the devices proved pretty inadequate. I've 30 odd of measured N but very few P. If any are any use please let me know.
Managed to get most of the SMD done today. It went much better for me than on my other SMD EUVL IV due to the bigger pads on this one. I got some new (different) solder recently and it isn't behaving as nicely as my last lot

And wow....I though I'd done a reasonable job. Then you zoom in on the photo and it isn't so great!
Maybe take another look at r64 and Rg beside jp2. But the rest look ok. A bit of flux and a retouch might be all that's needed.
Thanks Fran yes shall revisit some of the pads. I was annoyed I'd omitted the 820r Melf from my recent Mouser order so I have some 1% Yageo MF in there for now. Hopefully get the build finished in the next day or so, then to implement.!
I found it helpful to photo and zoom my SMD work to review it. Quite quick to do and very revealing.And wow....I though I'd done a reasonable job. Then you zoom in on the photo and it isn't so great!
Yes, I have one of those USB cameras from Aliexpress (quite good actually) and I use it to check over the board when I finish soldering the SMD stuff. Not for this build, but its especially good where you have 16 or 20 pin SMD chips to make sure you don't have any bridges and all legs are soldered properly.
All paid for GB orders were sent out this morning - you will each have gotten a mail from me with your tracking number. It takes 1-2 weeks to reach most places in the world.
For those of you who have ordered mosfets, they are all in the same pack, and please note the change in some resistor values from the BoM to suit this particular batch of mosfets - it is included on a separate slip in your pack.
Best of luck with your builds!

Yes I looked at the datasheet and compared it to your schematic and I was still non the wiser. I have no idea which way the current should be flowing I'm afraid.
Current always flow from positive to negative voltage.
Can never be the other way round.

I don't know how I missed this? Will there be another round or a chance to take over from someone who's dropped out?
I've been away the last few days guys - sorry for the poor comms over the past week.
I'll catch up on things over the next day or so.
