  • What is the etched 3+3 digit code on your E84Ls??? mb-de 08:21:50 05/15/01 (2)

    With these codes one should be able to tell who really made them.

    Generally spoken, Valvo in Hamburg was one of the Philips-owned valve manufactures, and produced very high quality valves. Though, often you would find valves from other Philips factories with Valvo logo - therefore my question for the code (Hint: Most "Valvo" EL34s I have seen were Mullard xf1/xf2/xf3s manufactured in Blackburn/UK).

      To my knowledge, Valvo Germany, Amperex Holland and Mullard UK have never produced any E84L/7320.

      Siemens is the only producer but I have been told that there maybe a French version too.

        Hello Tim!

        Indeed some Philips-owned French company produced E84Ls, as did Siemens and Tungsram for Siemens and others.

        Valvo sold E84Ls of Philips production in the 1950ies and 1960ies - I have got some databooks from 1961 where Valvo have a full datasheet of the E84L whilst it was not mentioned in my Siemens databook of the same year - but it appeared in the 1962 and 1968 Siemens books. Philips had it in the 1958 databook as well...

        This is the reason why I have asked for the code - to see where the valve came from...

        Regards,

    I believe Valvo never made any E84L/7320 and what you have are probably made by Siemens instead.

  Hi Tim,

  How about Siemens E84L?

    I ordered a matched quartet of Siemens EL84L and I didn't like the sound. Not well balanced -- hard upper mids and highs. Listened for a couple of hours -- and put them up for sale on ebay.

    I don't think they sound too good for EL84 application compare to the brands that were mentioned.

    But they probably sound great if you drive them harder than any EL84 can take.
