RE: Using the 6H30 "super tube" narrows the choice

While I now have several pieces of ARC gear that use the 6H30 I have only had one long enough to find out tube life on the 6H30.

My PH-6 phono stage definitely sounded tired after about 4000 hours. A new set of tubes brought back the magic. I would imagine the same will be true with the SP-20.

Generally ARC is pretty conservative on tube life and I can typically get good performance going beyond their recommended hours of use. But that has been with 6550 output tubes and 6922 small signal tubes. With the 6H30 I think they are correct on 4000 hours. Time to change.
