Things are busy at DIY Central... I also had PCBs manufactured for my PRE-1048 preamp (link coming soon). This time, I used a company based in Malaysia.  I got the PCBs today too, same day as my PSU PCBs.

Well, I'm a bit disappointed at the quality. Let's just say it's nowhere near the quality of the other PCBs I got manufactured here in the US. (See photo of article below this.)

There's also no silkscreen (but I knew that before I placed the order).... it's also more expensive than the US manufacturer if you divide the total price by the number of PCBs you get.

To their credit, they got the PCBs manufactured correctly. :)
