    I'm Chris.

    Default Mid price 300B valves

    I want to get some new production 300B valves at a price of up to about £300 per pair

    Lead candidates seem to be

    JJ £260pp
    Electro Harmonix EH £158pp
    Electro Harmonix Gold Grid £192pp
    Genalex Gold Lion £249pp
    Brimar £196pp (Possibly Softek sourced?)

    Any opinions or alternatives. Thanks

    All the EH models and Genalex are produced at the same factory, or at least they were a few years ago. They are then graded and become "Genalex Gold Lion" if they pass certain parameters. The gold pin EH's do sound better than non gold pin (silly I know) and are pretty much as good as the Gold Lion's. I have the Gold Lion's and I'm very happy with them.

    Not much experience with the JJ 300B's but I really like their KT88's. Lovely thick glass and a very well rounded sound.

    You have nice kit, I'd go with the Lion's as they're pretty much guaranteed to be the best of the 'non stratospheric' priced tubes.

    Excellent feed back thanks Chris. I would very much like to support the new Brimar venture, but can find very little in the way of reviews of their 300B. I have asked some questions on their Facebook page

    JJ all the way IMO in that price bracket.
    “Music has always been a matter of energy to me, a question of fuel. Sentimental people call it inspiration, but what they really mean is fuel. I have always needed fuel. I am a serious consumer. On some nights I still believe that a car with the gas needle on empty can run about fifty more miles if you have the right music very loud on the radio”

    I've read of unreliability with Genalex btw.
