No Problem...I will recall the invoice so it is not hanging around.
Best of luck in your new situation.

You are on the list. This is the last kit.
Unless someone cancels a kit order all 20 kits have been shipped/purchased/requested.
I still have boards and am ordering another bunch of IC's.
It might be a few weeks to catch up with all of the requests.
I will be sending out more requests for e-mails for invoicing this week.

All the best - hope things work out fine and you are able to get back to diyAudio soon.
Look at ESR and you chose...or try them both and compare.
The boards are for experimentation.
Have fun.

An externally hosted image should be here but it was not working when we last tested it.
Will be ok to mount Raspberry Pi running Volumio connected to Curryman dac and Dug's PTBL boards a 24v 5amp switching power supply for amps and linear for rpi and dac?
Looks good.
Personally I would use linear supplies everywhere. Need at least 1 amp supply for the pi - they are quite power hungry.
I understand you are going for a single box solution but I would separate the amp from the rest. There is a potential for a reasonable amount of heat in there. I have a BBB/Curryman DAC box and its plenty crowded without adding the amp!
I see that you also got the Samsung OEM SMPS power supply, have you use it yet? How you like it? I think this is one of the best SMPS I seen so far and I have been using it to power my 3116 amp too.
Here is how I install the IC's.
I've skipped the fluxing and soldering parts.
They are clamped in place. This allows me to position them right where they need to be.
I can pick up the board and look at the position without disturbing the IC's placement. Short of dropping the board the IC does not move.
There is approximately 350gms of force on each spring.
The IC's are spec'd at 1mm in height.
The tricky part is getting a heatsink that does not connect to other SMT parts that are thicker than that.
The heatsink mounting holes are 1.080" apart.
So to answer your question I can only say that 700gms should be OK.
And thank you for letting me know the boards have arrived...I am waiting for 11 other people to let me know.

I use a regular iron and liquid flux...and magnifying goggles.
I rest both arms on the work surface and use very strong lighting.
I would recommend a small tip temperature controlled iron.
I can offer no experience using a hot air system.
IMHO it would be more difficult for a novice to control heat with a hot air system.
There is a thread on here somewhere about this subject.
