Getting ready to mail the few I have now, awaiting more PCBs to arrive.

I decided to solder a DIP08 socket on the board to hold the opamp, best way to make sure the pins are not bend during shipping.

I'm probably confused, but the pics above don't seem to match the description of the 1/2 kit in the first post

- PCB;
- Current source LT3092 SMD soldered to the board;
- overload reset switch SMD soldered to the board;
- Pass device FDP12N60NZ;
- low current high brightness LED;
- depletion mode HV MOSFET IXTP08N100D2.

I don't see the mosfet, but I see an opamp I wasn't expecting.

Just wondering what I need to order to complete.
And since I'm asking questions, can you confirm the value of R6 and R8
Are they 10 and 3.3 ohms per the schematic markup?

Thanks
Randy

Randy, my bad, good catch. I didn't show the two MOSFETs in the picture but they will be included, as will be the high brightness LED.
I did show the opamp since a few people asked me to include is as well, for an additional € 5. I will post a new pic later today with the complete contents.

In the meantime, those of you who put themselves on the list, please send your name, email address, shipping address and a phone number to jandidden01 at gmail dot com as I will start to set up a spreadsheet for the shipping. In case you also want the opamp, say so as well.

I also put up a revised schematic mentioning thew dimensioning of R6, R8 and R11, (Vout & I-lim) referring to the links on the website.

I went back to the prototype and D3 is not a 1N4148 but a UF4007, just like D1 and D2. I also updated the online BOM for this.

A suggestion, for people like me who miss things I should have figured out,
change name of link
from "How to set Vout and Ilim"
to "How to set Vout (R11) and Ilim (R6, R8)"

Thanks for the answers. I currently have a CLCLC unregulated HV supply for my 45 based amp, looking forward to trying this instead.
