    Valvo Hamburg tubes are only E88CC and are very rare.

    First line of code will be 7Lx which identifies it as an E88CC

    Second line of code will start with a Dxx or Dxxx.

    Remember this tube is a late comer to the party compared to the typical signal tubes like 6SL7; 6SN7; ECC81; ECC82; ECC83, etc.

    The earliest tube is from about 1957.

    "Appreciation of audio is a completely subjective human experience. Measurements can provide a measure of insight, but are no substitute for human judgment. Why are we looking to reduce a subjective experience to objective criteria anyway? The subtleties of music and audio reproduction are for those who appreciate it. Differentiation by numbers is for those who do not".--Nelson Pass

    One of the tubes has what looks like a half circle with a dot in it and then 8A in gray text.

    The other has no gray text but has yellow text in that area that says 83 and then another letter/number that's been wiped off.

    GAx = production code for the ECC88

    7Lx = production code for the E88CC

    "x" being the change code (0,1,2,A,B,C etc)

    D getter and D getter w/pinched waist are early

    ring getter is middle dated

    closed getter is later

    closed getter w/dimples is later yet.

    This is general information for the Euro made tubes by Holland, Munich and Hamburg Germany and England.

    The first one is Ei Nis ( Elektronska Industrija) tube made in Yugoslavia in the late 70's early 80's. They made some consistently good tubes considered current stock then. The earlier the better as by the late 80's quality slipped. They supposedly bought Telefunken machinery and materials.

    not sure on the 2nd one. Have to see it.


    They (EI) had like wars and stuff to work around :(

    If, by chance, Brock dangles a Valvo Hamburg in front of you I'd suggest taking advantage of that opportunity.

    Dare I Google "Valvo Hamburg"? :p

    ... or ask Robin Williams.

    No doubt they look better with a glow to them...

    They literally just arrived today at my office and I immediately took those photos.

    I'll get them swapped in soon, but I'm evaluating some other gear right now that is taking precedence.

    Can't listen to a standalone DAC and a tube CDP at the same time!
