OK - let me tell you in other way - your link for pics isn't working

 

[UKToecutter]

Are you sure?

It works when I click the link.
It's a document, read only and there are two users viewing at the moment.

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

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

Andy
