---------------
I'm going to draw a line here and order some boards. Folks can keep adding their names to the list in case we have drop-outs or need to do a second run.

 

[Dennis Hui]

OK....adding my name:

First run will be €14.80/board (€29.60 for a set) + shipping.

Shipping by registered post is €12.70.

Hi Jeff,

I will wait till I know if I can get hold of any of the power fets from the GB by EUVL before I buy these. At this stage I am on a waiting list with not much chance it seems.

Gary..

 

[JeffYoung]

@Gary,

Understood. I'll leave you on the list till the boards arrive and then we'll move you down to the waiting list if you still don't know about the SemiSouths.

Cheers,
Jeff.

PS: boards were ordered today. Evidently EuroCircuits has enough business to be open on a Saturday.

 

[blackdod]

Thanks Jeff !!!

As for the transistors Gary, I´m in the same GB and I don't have many possibilities either but I prefer to have the pcb´s at home... you never know. 😎😎

 

[JeffYoung]

The Irish have a saying: "better looking at it than looking for it." 😉

 

[JeffYoung]

Note that I found a typo on the schematics: the target LTP current should be 8.5mA, not 9.5.

And for those curious as to how I got there, see the attached PDF. This is DIY (my professional life was spent on the digital side), so comments welcome.

Cheers,
Jeff.

 

[gary s]

I will most likely get the pcb's, you never know where a set of the Semi South's will appear from. Agree with blackdod.

Your analysis looks good.

If another batch is run, and in time others from Oz are interested in splitting shipping costs please let me know.

I assume you will let us know when we have to send the payment.

[MEPER]

I am also interested in a set of PCB's.
So if waiting list is possible then I would like to be added to the list.
