Mini LaFET PCB

I have finalized the my cut of the Mini Fet OPS. It should go out to the Fab house to tonight when I return home.

May I ask what the reason is for the ground fill?

 

[kool lites]

Sure. I couldn't get a clean direct connection from the filter cap pads with 150mil tracks.

Why are pads created that have "motes" around them, limiting the connection to the rest of the circuit to a "crosshair"? I've seen it done, but I don't know why, obviously. Perhaps it's just on the silk, as an indicator.

 

[kool lites]

Those little cross hairs are called reliefs. On this board they are 20 thou wide. They are used to improve solderibility.

You don't need to use as much heat compared to direct connection.

Cool! (pun intended). That is a mystery I don't have to ponder any more. Thanks!!!

Terry,
My boards arrived today.
Thank you.

VSHA-ECC88-IPS BOM

I started to pull together all the components for these boards.

I prefer to work off a pull sheet/BOM so I created the attached BOM.

I hope others find it useful too.

PS send any correction my way and I will gladly update.

That is awesome, thanks.

Could you also share with us how to adjust/test it, without OPS board?

 

[kool lites]

Happy to share my experience as I do so.
There are others here have more experience.

Well... As much as I wanted to do this project, it will be quite some time before I could get to it... So I'll sell only in a lot the latest GB parts I bought, which is the following:
2x KND
2x Slewmaster
2x tube ips that I cannot remember the name.

All I want is what I paid for them about 1-2 months ago.

PM me if you're interested or anyone else if alcroner is not a taker

Thanks
Do

I'm likely going to have a few sets of the Slewmaster output boards done in the next couple weeks. Does anyone have any suggestions for possible improvements in the layout? Did everything fit well? Are all hole sizes good? Does anyone want any boards?

 

[alcroner]

Im very interest of kypton nd ,i have from here now a Wolverine already which im happy with,
2 knd are what im need also,to the very good output stage.
Regard Alcroner

 

[evanc]

Jeff, I could put a pair of the big output boards to use.
Alcroner, I have some of the KND I could send to you.
