Luvdunhill sent me a few of the 'mistake' boards a while back - and likely more than I will use, so if/when they run out, let me know. 🙂
I prefer to send two invoices. This allows me to operate in a first come first served basis. It's easy - just send the purchase price when you express interest, if there are items left I accept the payment, send the item and request the remainder. Dunno, makes sense to me.
Ok, 2 fixed, 2 need fixin' are left.

I am also working on a First Watt style power supply. If you guys want another run of the FE boards, I could do it at that time.
I tried to buy everything together, I just expressed interest.
Do I need to pay first the parts and later the shipping and the rates for your paypal discounts ?
Best Regards

Enough ! Insulting posts deleted.
May I remind you both that the rules clearly state that any transactions are done at the buyer and sellers own risk. The forum is not responsible if things don't work out or you have disagreements.
I suggest you both take your differences over to private email. Any more such insults posted on the forum will see bin time for those involved.
Excellent. Working up a similar board that will implement the CSX2 transformer FE and a buffered F6 FE. Should be off to the lab by the end of the week.
Here is the CSX2/F6 ish FE
Here is a small discrete buffer that can be used in front of the transformer:
... and an example of a regulator that can also be used with this PCB:
Prototypes should be here soon - same price / process as the VFET2 FE boards.

An externally hosted image should be here but it was not working when we last tested it.

I can post the schematic / BOM for interested parties. Footprint and I/O to the output stage is the same as VFET2 - the idea is they can be swapped. A large number of transformers are supported, as the Lundahl's share pinouts across a lot of their extensive line. I can post a comprehensive list if people are interested. Enjoy!

I have sold all of these. I have one set that has swapped JFETs and BJTs - free, just pay shipping. If there is future interest, please register in this thread and we can consider another run. Enjoy!
