mea ookin' maxima culpa !
( what fooled me is "edit" on end of the link )
in any case - my main browser (FF) didn't let me to see files without signing in with my Gmail account , while Chrome let me see files anonymously

Fairchild 19N20 and 12P20
Teabag is true to his word!
When I got home today from a week of traveling, I have 4 pairs of Fairchild 19N20 (4 matched) and 12P20 (2 and 2 matched) outputs.
I will be glad to test the board.
UKToecutter, I will PM you to give you my address.
Can't wait!

UKToecutter,
Check BOMs , R26 should be 10k=R25

JJ,
Check Papa's schematic. R26 is definately 47.5k

UKToecutter,
Can you put each board size on the file, thanks.
JJ
Sure, no problem
F5 V2 BOM
Andy,
I was looking at the BOM for the V2 and I think R3 & R4 (10 ohms) should be 1 watt. At least they were in the standard F5. It may be hard to get 1 watt resistors in the space provided, but I will stand them up if needed.
That's the only thing I see so far.

Rush,
I have found a Vishay Dale 1W 10R resistor that is 7.37mm long so that should fit lying down.
I'll check the original F5 documentation and change the BOM's.
Thanks

I think you're right. We'll go for 1W
