Done Assembling!
I finished building my PowerPhysics A-154 Class-D power amp! Yeah! It's taken a while, but actually went pretty smooth. Attached are two pics showing the completed unit. The next step is careful and thorough bench testing. With that, I will measure and verify noise, stability, bandwidth, gain and of course, power output both stereo and bridged. This is usually fun and progresses pretty quickly. Yet, it can be a bit nerve-racking the first time cranking it up to full power into a minimal load pushing the limit of the whole system. But, this can also be very satisfying when the amp performs well and remains stable and cool while belting out gobs of power. Sadly, this can also be the moment when countless hours of hard work and toil can go away in a silent wisp of smoke or a gruesome cacophony of melted wires, trembling transformers and shorted outputs.
Assuming all goes well, the final step will be the best part: the listening test. I'll report back to DIY when this step arrives. Regards, Paul

What was the cost on these? Can you order thru them? or do you have to use a distributor? The A2-154 looks interesting....

Has anyone purchased and/or evaluated the Power Physics A-1014 1000 wate class-D amplifier and the P-1000-115 power factor corrected switch mode power supply ??
I'm trying to get some information about its performance and functionality but the owner seems to have gone missing. PowerPhysics Audio Electronics - A-1014 |
