    Hi Eckhard, it's me again

    this is the right question for Giskard.
    I can imagine, that they (JBL) have a detailed list with the numbers (for guarantee problems) and are able to find out the fabrication year.
    What should the numbers be for, if not for this???

    I know for a fact that this is not the case. The Northridge earthquake back in 1993 destroyed the majority of JBL's production records. Therefore, they have lost the ability to correlate serial numbers with year of production.

    I have a D130 serial # 82039 that I'd like to hear any guesses as to its age.

    Well, since you're asking for guesses...

    I have seen D130 serial numbers as high as 90661 so I think your 82039 serial number would place it kind of towards the end of the line in the mid to late 1960s.

    Just a guess until we get more info in the serial number registry thread

    Hi Sluggo,

    the JBL-Registry says:
    No. 26536----> 1957
    No. 40812----> 1960

    highest No. in the Registry: 212167 -----> ??

    The D130 was first built in 1948 and the last in 1977 (unconfirmed)
    Glen maybe right with his assumption mid to late 60's

    Hi HP,
    The 212167 (may actually be 212147) is an old cutcorners label, presumably from December of 1952

    Thanks for the warm welcome HP. I could use a little help identifying the cabinets.they're rear projection bass reflection, The only identification I have on them is a sticker inside each cabinet that reads.....

    To adjust R4 cabinet response space this plate from bottom opening in cabinet with the exact number and size of spacer block on each side as listed below. Suggested settings found suitable for popular speakers shown (these setttings do not necessarily correspond with resonant frequency as given by manufacturer).

    20 cps one 1/2" spacer

    30 cps two 1/2"

    35 cps one 1/2" + one 3/4" woofers stephens electrovoice
    woofers

    40 cps one 1/2", two 3/4" free cone speakers stephens 15"
    and 12", Electrovoice 15" and 12",
    JBL 15" and 12", altec 15"

    65 cps remove plate and university and Jensen 15"
    spacers



    The demensions are 24"X24"X18" depth with a very nice finish will get pics if you'd like.

    Thanks Steve

    I run these with a 1959 EICO HT-91 kit tube amp and an off the shelf sansui cd player at the moment listening to alvin lee and ten years after pure blues (a pure delight) heres the kicker total cost of this orgasm of audio ...fifty cents(the sansui's a loaner) i guess what i'm saying is i'm hooked i'll never go back to solid state again I mean this modest little system puts my ex's and now my ex 500 watt kenwwood and 901's to shame ,I'm in love
