Tubes don't get much love in these parts, and reasonably so, as tubes are an anachronism these days, and the commercial side of the tube realm is completely under control of the Dark Side. But having had the chance to look up the skirt of a Prima Luna amp, and having rolled a few of my own, they are very well done (lead dress, wiring layout, etc, you know, the sort of thing that makes my home brew amps look like a real birds nest).
