Yep, B3-080.

Very cool. I was contemplating the sigma 25/24 combo in that case. Looks like it'll be a very close fit with the transformer? On the other hand it seems the amveco low profile transformer would fit in the case easily, so that might be a better route than the sigma24.

Easy until you account for the wires.

I guess it would be a lot easier if you omit the IEC and power switch.....

Wow, Mouser had around 1000 or so OPA2365 in stock yesterday, and now this morning they're all gone. I should've bought an extra or two

I'm pretty sure they were just filling backorders. They were never actually available to ship to new buyers

I estimated 1000 because when I visited the page there were 92x in stock, and was thinking that 80 had the backorders fulfilled. I ordered from Mouser just yesterday and one of the chips is coming my way. I kind of doubt that 900 were rushing to buy one for their y2, unless the demand for the y2 is that high. Only Ti knows

.

Edit: Seems like Newark has 700 in stock. They were out yesterday.

True, I hadn't given the wiring too much thought as I was worried about getting a transformer that would actually fit. Very neat wiring there MisterX, I'll give mine a shot as looking nearly as neat and organized that is

It works now, thank you !

Finished! Went together with no issue's. Testing atm, and no smoke, yet! This little p/s is outputting 5v (5.01v to be exact) no sweat, and the interferance noise from my pc has completley gone!
happy times

The chassis is the same as the y2 DAC, but 1.5cm taller, which was need to fit the trafo. think the led looks awesome...

Pretty cool, we don't see hand etched boards around here very often.

Which gets hotter, the transformer or the Heatsink?

both are pretty warm, I am going to use a larger heatsink on V.reg, which will help. The case itself becomes warm when closed up, ventilation hole above the trafo may also be a good idea, for long term reliabilty.
edit. just tested dc out and it has fallen from 5.01v to 4.98 after 1 hours use, is this a heat issue?

The voltage regulator does have some temperature coeffient, but I wouldn't worry about a slow 0.03V change over time.

Thanks, is it the heat that is causing the 0.03v change?

 

[amb]

By "temperature coefficient", that's what I inferred.

 

[dean0]

okay thanks

How much current does the y2+y1 draw? I understand the y2 draws 150mA, is that for both?
Thanks Again
