Dare I venture my definitive and humble opinion on the strength of many tubes that have crossed my threshold (and connected to my power circuit): C.A.T. Ultimate for line, for phono -- JP200 as per rcprince & detlof and SRPP (you had to build that one yourself. It had provision for 0,5 farad power supply for phono, direct line for *aux* with interchangeable capacitance loading and *silver alloy* recommended for internal wiring -- back in the late 70s!)
Admittedly, the CAT & JP80 are great all-rounders if U can afford them. SP6 & 10 are nice too, a bit ageing, however...
