Strosek,

Would you mind sharing your BOM with links to suggested components (if it's not too much trouble)? 😀

Strosek said:
Quanghao, the circuit for SSHV posted above lists for D5 & D6 - 1N4142A but the BOM (on page 179 of the original thread) says 1n4172?

I suspect the part we want here is 1N4742 or 1N4742A a 1W 12V Zener Diode....

Is this correct and if it is could you please make the corrections to the circuit so others don't have a problem.

Thanks!

If I had one I'd be happy to share It but all I did was use Quanghao's BOM and I just held off on ordering parts that I wasn't sure about ie. the diodes I just posted about.

I sourced most of the parts from Mouser, Digikey and just a few things off ebay.

I'm 95% done... I held off on the diodes and power supplies which I'm hoping to get from Bud P if he ever responds to my PM's.

If you need specific assistance with a certain parts please PM directly and I'll see what I can do as I do have many extras.

Thanks!

Thanks for the link and price!

One quick question, in the BOM, there are 1/4W, 2W right next to resistors. I assume these mean power rating of resistors. The spec of CCF50 says it's 0.33W so it can handle 1/4W OK but how about "2W" on the 33 ohm resistor?

Hi !
I got to the final! But something strange happens to 6.3V power supply!
AC voltage is 12-14V/ 3A! After about 15 seconds the relay flashing and DC voltage increases and decreases between 2,5V - 6,3V! I use R 80-36 R core transformer from DIYCLUB! Which may be the problem?
Thank you!

12-14V AC, it´s not a little bit to high? All the scheme says 6,3 -9V.
