The rectifier boards arrived today.
For comparison, the board to the left is from PCBPro. PCBPro has somewhat crisper silk screen, but the 10mil Olimex silk screen is fine.
The Olimex boards have a slightly rougher cut edge then PCBPro. Not something I'd even noticed until I looked at the photos.
For RoHS compliance Olimex has gone to immersion gold. Very nice. You can't see it in the photos but some of the PCBPro boards had significant solder puddles. Not a big deal, but Olimex is a clear winner over PCBPro here.
Minor gripe. I sent the Eagle .brd file along with my Gerbers. Olixmex used the .brd file. In the .brd file, the board outline and the Rev 0.4 text were in non-standard Layer 121. Olimex took everything in 121 and put it in all the layers. -- So I've got copper and silk on the board outline. I've also got an reversed Rev 0.4 on the bottom. I pulled up the copper from the board outline. No big deal and looks fine. I should know better then to include a .brd file. I only sent them Gerbers for the regulator board.
Overall I'm quite pleased with the results. Price was good 47USD for two including shipping from Bulgaria.
The regulator boards should ship in about week and be here in two.
I've decided on an Aikidio configuration. SPICE says it will idle at about 35mA for a Stereo pair. I'm going to get a transformer and choke in the 60mA range.
