We have just placed order for the V2 boards.
They include the F5-HA main board, 317_337 Cap Multipliers, and Mod. Linkwitz X'fd Buffer.
We shall also include 2 (untested) new features which are optional, at no additional costs.
They include a DC servo using OPA140, and a fully configurable headphone protection circuit.
We shall Beta test all of the above with one of the V2 subscribers.
He thinks he will need 3 months or so.
You will only be invoiced when the Beta test is ready.
So please be patient in the meantime.

I have been asked about mechanical parts to go with the 2107 case.
The JFET heat sinks are not included but can be ordered separately.
They cost HKD30 each (we don't have stock, need make to order).
We shall not be providing case or angles or another other machined parts.
Our factory is 120% loaded and they are way too expensive for such simple parts.
You can easily buy suitable aluminium angle profiles and just cut them to size.
Or just bend them from soft aluminium or copper.
Please see examples in the F5-HA Build Thread.

(since this is not for balanced version I only need 1 board -- but if no one else wants the board I'll take the second one -- it was my mistake)

Been pondering ... turns out I have 8 LU1014s matched at 1.20 sitting in my shop, so the DAO SE is looking really good, I also am in for the balanced F5HA and can easily wait 6 months. So, if it isn't an issue I will wait.
Thanks for all your outstanding work!

I do hope some of you will build something during the holidays, whether Vero or otherwise.
It is so simple, and yet so rewarding.
Just ask those who have been listening to one for some time now......

Hi Patrick,
Planing to start the build on the simplify version close to you prototype board (no cross feed ) and separate super reg for +-15VDC while wait on the M2 PCB.
