    JBL tube amp?

    Do you know any history of JBL's tube amp production?
    What I know is JBL produced some solid state amps in the 1960s and 1970s.
    I see one called JBL 5120 tube amp on eBay.
    Any idea?

    Provide a link
    Only thing close is a couple listings for some of those old Ampex suitcase deals with JBL speakers
    I don't think JBL ever built any tube amps for sale but I could be mistaken
    Post a link to what you are asking about
    There were some costco cheapies by that designate "J5120" back in the early 1990s

    Tube for Hartsfield

    In those days JBL offered a powerful sophisticated tube amp for the Hartsfield.
    It was created by an external developer.
    For details I should make a search.
    This amp is unobtainable today I presume.

    Thanks so much for your efforts! New discovery for me. By the way, JBL 5120 tube amp is a mono, not stereo, I hear.

    I looked only a pair of those Ampex suitcase deals
    Why is everyone willing to ask a question but so shy about posting a link to the object of their inquiry?

    No one thought to save the photos?

    Would someone please post a link to the original for sale listing if you've already found it?
    Thank you

    Thank you very much!
    I searched completed listings using almost verbatim the ad's heading and no go - ebay is strange that way sometimes
    I've had this happen before - a friend and I were on the telephone and he's giving me word for word his search criteria for a pair of speakers we were interested in - but the pair of speakers in question would absolutely not show up on my screen - not until he emailed a link and I plugged that in

    Enjoyed the photos. Reminds me of an old Seeberg juke box amp I used in my first hi fi rig in the late 1950s! Actually didn't sound all bad - lots of power for those times. Turned it into a two-way rig. Needed a better enclosure. As we often say here, good hobby!

    The seller relisted this item. Actually I contacted the seller on this, and was told this is a MONOblock, not stereo.

    One caveat for those interested in this item: this amp is a MONOblock, not stereo. The seller confirmed it, though he failed to mention it in his description. So, think carefully if you want a stereo tube amp.
