  • 15" excursion rattles

    Here's a D-130F 8 OHM.
    Secured with five fasteners.Notwithstanding the 122 middle back cover and 147 amp.
    Looks like it's been in there for a long time.Bottom's out,paper on wood.
    Awful is my only description.
    Once a Jensen 16 OHM is back in there it might behave better?

    Dusty 147 missing output selector dial,still has factory Tung-Sol 6550's.Appears to be an original can cap too.
    Actually sounds fine until the woofer draws too much current. V21 sounds great so far.
    Out of balance load not behaving,the X-over simply can't handle an 8 ohm 15" without moving the x-over frequency.
    Will clean it up and install Jensen P15LL?

    Here's hoping.Funny the D130F-8 sounds just fine in the place of a 4 OHM load in a 760?

    It really isn't a surprise to get a 147 amp and a 122 middle back cover.
    Matches up with the opposite,like that pair of socks....

    Pete I had an 8 ohm E140-8 in a 760. Just tweak the amp balances and away you go. They were supposed to have a spacer ring on them when used in a Leslie. I found an mdf ring cheap on eBay. That being said I prefer the stock sound these days ;-)

      The JBL D130F is the full-range version of this speaker, designed for lead guitar. For extended highs, it has a low-mass edgewound aluminum voice coil, even-hung, the coil the same height as the gap.

      The D140F is the bass version with a heavier copper voice coil.

      You could sell the D-130F to a guitar player with a Fender Showman, in which they were original equipment. Their extended high-frequency response is somewhat wasted with an 800Hz crossover, which becomes a 400Hz crossover with an 8Ω driver.

      I recently reconed a 1971 D120F, which is a very tricky recone to get right.

        A Vibroverb or Steel Guitar amp or Showman or Concert would benefit a little sparkle so yeah,will try and steer it that way.
        This P15LL will make all the difference.

          Tested the box with a fresh P15LL. Love it. Hardwood baffles November 1967 '3337'.Cleaned and adjusted hanging off a really sweet 1961 A100(7514).
          Found the control knob for the output selector buried in the bottom,the usual 50 years of dust.
          The A100 reverb (AO35) is fed through a 47 ohm resistor and mixed with the AO39 to a '26-1' Leslie plug box which has no 5 pin plug.
          It's been 'hard wired' instead,which in this app is fine by me.
          Checked the wiring,it's all fine.
          This rig(A100/147) is ready to do a recording.Can barely hear it running, no bad hums.

          A JBL D130F-8 has become available.
