just remember to change the orientation of the LMZ...that is wrong in this schematic.
If you cannot source BSP129, you can also use BSS129....like in picture i posted.
😎
CeeVee do you have a drawing of your pcb? What brand are the blue resistors?
What about a SMD version for more space saving?

CeeVee, would you happen to have any spare PCBs lying around? 😀
That looks like a nice piece of work.

...no, i just etched 2 for testing and only one survived 😀
it's pretty easy to replicate and i can tell you that all i see in my cope with this thing loaded is a straight line...very, very quiet.😀
This is the BSS129 version of the board:

BSS is throughole package 1W device and BSP which is SMD is a 1.8W device.
However first one will do for the specific application if you can't get BSP.
Although you are in luck because Mouser has the BSP129 in stock now, just checked🙂

Moreover, BSSxxx (TO92) are discontinued since long time and Siemens/Infineon is manufacturing today SMD only.
CeeVee, if we drum up enough interest here would you be willing to fabricate the PCBs for those who would be willing to buy them from you? Boards only; end user supplies parts.
We will see, i would suggest to wait for the draft design of Shiga PCB and i could redesign PCB to fit neatly on it with 3 pin terminal.
BUT and here is a big but we should first ask Peter Daniel if we can do this since he was the one who published the design !!!

Ooops - good point - didn't think of that though the sketch of the design was
published for us to p2p copy wasn't it ?

The design is actually Bobken's, and he is happy for everyone to use it.
Please keep in mind that his reg is so good partly because all its components have been carefully selected "by ear". In other words, I suggest that you stick to Peter's recommended components unless you have a good reason to deviate from his choices (like the expense of buying a 10uF BG N).
Current "youpay" 1- pair 2200 =GBP 100
1- pair 10 =GBP 40
I think not for me, will look for a different solution.
Yes, it will be a bit pricey. What are the total voltages needed? I see at least +8 VDC and +5 VDC. Anything else?
Black Gate FK are not a part of the regulator itself, they are just in the Peter's recommended PSU configuration.
If you can't afford Black Gates, consider using a 2200uf Elna Starget and a 1000uf Sanyo Os-Con instead - they sounded best in my extensive capacitor tests. I would also pick Os-Con for the 10uf position as it sounds slightly more accurate than Starget, but some people prefer the warmer Starget signature. Stargets also benefit more from wood-modding (if you take such things into consideration).

Should the big 3W resistor be 3 or 15 ohm?
According to the sim 15 ohm leads to 0.017A CCS. Am I right?

I've started gathering components for my Shigaclones, and have a nice section of copper plate for the base/bases.
the plate measures 10.5" (26.7cm) X 4" (10.16cm) X 1/4" (3.56cm).
Is this large enough for two units or should I just use it for one? It seems quite massive compared to the transport mechanism.
