Hey,

yesterday, my Model 70 PS died.
It appears, there are two vendors, who built these 132W PS's:
EU: Procond Elettronica (Made in Italy) and
US: Astec (Made in HK).
Mine is the EU Model. After opening it up, you see lots of flux residue, many solder blobs, solder inclusions and a sketchy PCB layout: Components were severely bent, so they can fit in their position without shorting each other. The taped-together 3-sheet-paper insulation between PCB and PS-Case is also nothing i'd expect in a machine with that price tag. Does anyone have some photos from the inside of the Astec AA15530 (the US model)? If the layout is as shitty as the EU Model, I'll pass on ordering the US one and try to replace the internals with a FlexATX PS.

Regards,
Stefan

The ASTEC arrived yesterday from the US. https://photos.app.goo.gl/PGmw794fXyzvdrdY6 Time for a comparison.
