I think that you'll enjoy these>>>Quad of SED Winged C 6L6GC's, as far as new tubes go.
Very nice amp.
Elegant and simple.
Are you considering a tubed phono stage? A Manley Steelhead is excellent ($$$), but one can't go wrong with a used JuicyMusic Tercel II or even a Bottlehead Seduction if you're feeling adventurous and are handy with a soldering iron, but I suppose that the look is a consideration with your very pretty cabinet.
