OM3LZ version 3 power supply BOM needed


 

I need the BOM for the DC-DC? converter for N2PK by OM3LZ. The board has a 2009 date on it. This is his third version according to the website.

Hopefully someone has a copy.

G'day Jim.

I have a BOM; see attached.

The original is in Excel/.csv format; contact me if you want that.

I also have PCB and overlay drawings in .pdf.

I looked at his website; the third version is more complex than the one for which I kept data; I built my VNA in, I think, 2007 so the data that I have is for an earlier version.

It must be version two as it's different to version one..

I didn't build it; I just made a simple 5v & 12v linear supply with simple zener-based over-voltage protection.

It has never failed.

It looks like v 4? has a schematic with the part numbers. Since it is very similar to v 3. I may be able? to figure out which parts will actually fit on the board.

I try? to source parts for several projects at once to lessen the impact of? postage costs.? The trick is? to order all the parts and not leave any off..

In carpentry there is a caution, measure twice and cut once :) I have to check the parts lists several times to avoid disappointment.
