re: RA-412

I just rebuilt mine (new-old-stock transistors, new cement resistors and all new caps + a careful bias) - sounds amazing through a pair of Wharfedale 3 way speakers, you just stare at it in awe, wondering why anyone would pay £1k for a system that sounds "just as good if not worse" - when I paid £30 for the amp and a matching tuner..
