Once the GB starts to close, I will send out private messages and post here that it is about to end.
excellent, thank you.


do you have a rough idea on the shipping cost for a full kit + board to Australia? You mention they "will demand a significantly higher shipping costs as the heatsinks and caps require package shipping internationally." which is to be expected of course, I'm just wondering how significant that cost might be.


I'm sure it'll be worth the convenience (and could well be cheaper anyway if I'm forced to source parts from a few different places), but I figure I've got a little bit of time to do some research.


Thanks again.

(not sure if has ordered full kits or just boards) @Drone7 is from the same 'neck of woods' sort of speaking so he may be able to comment; he is an extremely helpful chap so a quick message will do...

Default GB for Salas L-Adapter Board

Hi Tea Bag,
I asked Salas if it was possible to use the L adapter with minititx Pc. He replied below. I was wondering if it is possible for you in the next Gb custom replace with the below components that Salas recommended. (Not the transformer). I would buy a full kit, but with the replacement parts below.
Thanks

Hello @salas, I have a Windows Pc-based Roon server with the following configuration, Gigabyte mini Itx + i3 + Ssd + Hd4tb. The consumption is about 120w 12v. I have been using regular (notebook like) 10a Smpsu, but I have had problems like voltage drop and also sudden shutdowns. I wonder if the L adapter would withstand this voltage and amperage. If so, which transformer is recommended. Every help is welcome. thankful
That's on the limit of L-Adapter but it may still tackle it with big 200W MJL1302AG Q2, FFPF30UP20STU or alike 30A bridge diodes, 10A slow blow F1 fuse, 22000uF/25V C3 C4 of >5A ripple current spec each, 1000uF/25V C2, 15VAC/200VA toroidal transformer like Antek AS-2215.

Of course Q2 and the bridge diodes should be insulation mounted on big external sinking surface(s). With fins correctly oriented and well ventilated or fan assisted. Thick gauge output cables of no more than necessary length are a must too.

Will try to work with Salas for a even higher powered output kit, see if it get's some momentum. In small quantities, it will cost people more than buying the parts yourself more than likely.

The bridge diode is already that part FFPF30UP20STU.
