Anyone got any experience or opinions on this amp? Its got 2 EL34 valves in class A single ended mode, produces a claimed 12W and sounds pretty damm good as I'm trying a 2nd hand one at the moment... does anyone know what it originally cost new? The one I've got is a bit tatty but sounding fine, not sure what the seller is expecting price wise yet. It doesn't look like its made anymore, and can't find mention of it on the web. Thanks, Alan
