as delivery is so high of EVOX RIFA SMR: C6, C8, C9 and C21 (and difficulty finding them), i've bought 8 extra from sweden if anyone needs them. PM me to let me know. i'm not looking for a big profit, just trying to help out.
only just bought them, so they'll be a little while coming. UK delivery for 4 incl p+p will be 5, OR 4 if you haggle!


((the items bought from sweden cost 13.33euros, plus taxes and shipping = 41.68 euros!!!!))

Is there a particular seller that offers the boards without the 3.3 and 5V regulators pre-soldered? I was thinking about one of the cs4398 boards but that might limit my choice.

Also if they are fitted, what would the harm of wiring new supplies to the outputs of these regulators (there would be no components installed on the supply side).

Exactly, thanks for reporting the typo.

I've just updated the spreadsheet.

i think from the erin's original post, that is the seller he or she used. or i definitely remember reading about 'along'. maybe do a search for 'along'. sorry, not much help, am i!? i'm pretty sure from reading in the beginning that they come 2x15 and 2x9, but i can't tell you for sure. have you mailed the seller in ebay??

be aware, i'm a complete noob! but, i've read that if you're gonna follow dario's (clave) BOM, then it might be better to buy an unpopulated board and follow the BOM and images/schematic.
by de-soldering a populated board to change all according to the BOM, runs the risk of damaging the board and/or making it messy.

just what i read somewhere, if it helps (althought i see you've been a member for some time, so your skills are probably good

For what it's worth - I would prefer to buy a complete kit, build it, test it and use it over a two to five day burn-in. When you are satisfied, then upgrade. I have done ten or twelve builds over the past three years an this approach has given me the best results. If something goes wrong it is easier to troubleshoot and get advice from both the original vendor and the members here on the forum with an "as published" build.

If you are a seasoned builder and understand how easy it is to get the wrong part from Mouser and other distributors (even sometimes when you have the part numbers) then I say go for it.

Dario's BOMs are excellent and proven to work if constructed correctly. The cost/waste of the two step method just adds some predictability and reassurance to the new DIYer. I haven't added up the cost of the leftover parts from build - then upgrade of this DAC, but it's a bargain compared to potential hours and hours of recovery activities.

Just my two cents.

BobM,
wise words and that is why I bought 2 boards. I know from bitter experience though that PCBs do not like too much soldering and we already know from others on this thread that this PCB is a little fragile.

When I started kit building there was a very experienced E/E on that kit forum that advised to 'only make one change at a time' otherwise ' you lose any point of reference'.

So I would add where you know that it is likely you will try different components use pcb pins or solid core copper wire to solder to - saves a lot of trouble.
