    I used to use RCA long black plate 12BH7's in my Croft Series 4s and found them the "nicest" of the 12 BH7's I tried. I liked them much more than the RCA grey plates. I find a 1960's vintage Raytheon 12BH7 hits the sweet spot in the 25RS line stage.

    Thats good to know. Ive had it on good authority that the 50s RCAs are the best. Can you remember how the raytheon differs? I need to buy one more for my linestage but dont know wether to wait until i hear the RCAs first or take the plunge on something else

    In the line stage the Raytheon is more "open and transparent" with better fine detail than the RCA. The RCA has a fuller mid range "bloom" but to my ears the Raytheon suits digital replay better but YMMV.

    Hhmmm this has got me thinking now. They are definitely three of the characteristics i like. Although i very rarely play digital music unless I stick spotify on for the missus. (She’s forbidden from the turntable , far to clumsy for that haha)

    Can you remember what year and lettering it was Steve?

    Thanks

    Afraid I can't remember. I bought it from Drew of this parish (user name da2222). He is a fantastic source for guaranteed quality NOS tubes. He's currently got a post on Private Exhibitions for NOS ecc82's but drop him a PM about 12BH7's.

    No worries mate, i actually messaged him last night but he doesnt have any 12bh7A at the moment. Theres a couple of 50s and 60s black plate raytheon available in america for 40-50 usd. Not too badly priced. Might be worth a gamble?

    You could also consider a Westinghouse 12BH7. There is actually one for sale on AoS at the moment.

    I think you'll be absolutely fine with the very nice NOS valves you've got already.
    Looking back on my own experience, the only change I'd consider a priority would be swapping any ECC99's that might have been fitted for NOS 12bh7's.
    Apart from that if someone were to sneakily replace my carefully selected NOS valves with others I'd rejected, I reckon I probably wouldn't notice the difference.
    You can get really hyper about these things when you're "in the zone" and waste an awful lot of time and money.
    That's what I reckon, anyway.
