    Default SCORE!

    Just snagged a matched quad of NOS 1959 RCA 5691 Black-plate Red base’s from a chap in Spain. Only been on the tester, never been used.

    Should do me nicely for a few years.

    For my buffer stage. It has two valves rather than four, so two will go in the ‘cupboard of Hi-Fi paraphernalia’ for a couple of years or more.

    They should do 10000 hours anyway, or about 10 hours 365 days a year for the next 3 years!

    Ah - your AD Audio design. Are they an alternative to the 6N9Ss?

    What he said. The 5691’s are the holy grail of 6SL7 replacements. I have the Melz 6H9Cs in at the moment, which are very very good indeed, but these are the best of the lot apparently.

    The buffer is on around 14 hours a day (on when I wake up, off when I go to bed - the system plays pretty much all day). That’s about 5,000 hours a year so these should do me four years, or more hopefully.

    Have you got the 5 hole version of the Melz? If so, interested in selling?

    No sadly, they’re the solid anode version. Although I can’t imagine how much better the holed versions are - they are absolutely incredible valves!

    They are the metal base OTK versions of course.

    Crikey o’blimey! These 5691s are GOOD! The differences between these and the excellent 1950’s Melz metal base OTK 6H9Cs are not vast, but there is a difference. I’ve only had the 5691s in for half an hour so they’re only really getting into their stride, but the noticeable areas are bass weight (deep and clear, and also more impact) and the presence in the midrange.

    I’m only watching the tele at the moment (Lucifer - if you haven’t seen it, it’s great!) but even with Netflix’s fairly poor audio processing, the 5691s show their prowess. I’ll do some serious critical listening after I have a couple of dozen hours on them, but already I’m impressed.
