You can clearly see the "leakage", but at a second look you may peek traces between second and upper third row.
-
I may post a picture if I can catch it with my crappy phone. It looks like leaking copper around the holes, but I can also see direct connections between adacent holes.
-
Yes, this is the only area of both boards with bad looking traces around the holes,making undue connections. Think I'm going to salvage them, helped by the gerber's bottom copper traces.
-
Yep, a shrunk blue board. But the one I have on hands have connection between each and every one of the 6 holes, both vertically and horizontally. Of course nothing is soldered to it yet.

While going very slowly, I inspected my blue board PS and have a question. It looks there is a mistake on it at filament relay. Are the 3 lower rows of pads supposed to be connected together ? I have continuity from a row to another (except the upper row obviously).

So classy, thank you !

Big children are happy with weired toys... At least no Lenesas here ! (always crappy pictures with me)
-
Any finished system here ? I also would like to know if mpsa are OK for the ubal to bal boards ? And what is the proper way to use them with dynalo mk2 ? Thanks
-
Wow, massive madness here ! Can't wait to see it built.

Just build one yourself ! We are waiting for your thoughts and tweaks
-
It looks good all SMT. And quite straightforward. I have just finished Sjostrom's Qrv-08 today, which is trickier with it's massive PS.

Texas components make them to order with no additional cost.

I am interested indeed !
-
Copied. I'll order the through-hole version as I still have some MPSA/MPSW
-
One set is two boards ? I'm in for a balanced dynalo.
-
Add a randomisation, and the doctor will receive what the patient's doesn't know giving (sorry that sound weird) !

Thank you GeorgeP.

Dr Gilmore said that the LED must be 2.1V. I've ordered the recommended Lite-On, and they appear to be 1.9V on my cheap chinese tester. I presume it's alright ? Another question regarding the 3W resistor. The old BOM says 3W, some PCB say 1W. The 5.11k one is stocked at 2W (Vishay/Dale), not 3. And could be obtained at 5.1k (Vishay/BC)... This has already been discussed, but I can't find that info. Thanks

Thanks luvdunhill

Not exactly part sourcing, but I need an advice. I'm planning to put my DAC in a case, but it's using an old fat EI-core transformer. I would like to take the 2-boxes way, but where am I putting the PS boards and chokes ? Boxed with the transformer, or with the signal stuff ? I read that chokes are sensitive to EMI... I'm looking to keep the PSU's impedance as low as possible. Any idea ?
-
gepardcv, haven't measured it myself, but this supply -despite what they say about it- is very noisy. Some have experienced this at DIYAudio. Personally, I wouldn't dare.
-
And as they are fat bottomed, they need larger wires too...

Great and ambitious lineup ! I'm also stocking things for this beast, but being a slow builder it's going to take several months... I'm gathering mods ant tips in the thread for now.
