Raul, Sorry for the tone of my post, if it was too intense. In response to your latest, I can only say that there definitely ARE reports on the internet, on various other sites, of SP10s that won't hold speed, that have lost torque, that are plain "dead", etc. It is not unlikely that many of these problems were caused by old electrolytic capacitors that had become leaky and then destroyed downstream transistors or ICs. As Strathorncat said, I don't expect any "improvement" over the basic as-new performance of a fully functional SP10 Mk2A.
Stay tuned for the battery-supplied SP10, however. (Not hard to do for the 5V supply.) That would be cool.
