They still seem to command a reasonable price second hand would they have been in the same league as the old c-Audio SR range in terms of build quality sound quality and balls?

The 'switching mosfet' is a misnomer and a dubious marketing ploy. It simply means that they used mosfets in the output stage that were primarily designed for switching use rather than linear use. The amp has a standard transformer power supply and a linear output stage.
They're a nice quality amp though, at least as good as an SR, if you can get a clean one. (the ecler and the SR both suffer from corroded steel and flaking powder coating!!). Common faults to name two are failure of plated-through holes and rusting chassis causing the powder-coating to jam the fans. |

+1 Yep, their chassis are terrible quality. The front panel/grill is somehow better coated but the rest is very poor.  Edited by M4trix - 29 April 2016 at 10:18pm |

I actually wanted to suggest a flight case for such amps, especially for outdoors and rough handling. Btw, take a look here. It's Leco's website (Romanian language) and shows your amp inside. Not much to see. A simple ol' skool amp.  http://www.forum.poweraudio.ro/viewtopic.php?t=6623 Edit: SMD parts are on the bottom side of the PCB. Edited by M4trix - 29 April 2016 at 10:46pm |

Yep, those are ferrite beads and they prevent possible oscillations. Place it back on the gate. The explanation is on the picture.
