  • Anyone know what L100 reverb tank input and output transducer impedances are?



    My L100's reverb hasdied. I suspect the input and output transducers have broken fine wires. I get an open circuit reading on the meter on both input and output sockets. Does anyone know what their impedancesare supposed to be? It's a Hammond / Gibbs 4L, 1122-6646 tank, AO-23580-11.</P>


    Cheers</P>

    I have found that Accutronics still make the original 4L reverb tanks. Their part for the L100 reverb tank is 4FB1B1C and you can order them online from their www.accutronicsreverb.com web site. They were very helpful and fast in their response.</P>

      Are you sure about that part number? I tried to pull it up on their web site but got zero results.</p>

        Yep...</P>


        The Hammond Organ part number A0-23580-11, Gibbs model 4L, is the same
        as an Accutronics model 4FB1B1C reverb unit. The cost for a
        type 4 reverb is $32.00 usd plus $11.95 usd for shipping and handling
        within the continental USA.

          That's cool. I cannot find it anywhere on their web site. Is that just the "tank" with the springs, or the whole thing with the pre-amp/amp that sits behind it, as well?

            It is just the tank. Accutronics does not make amplifiers, but Trek II makesa complete unit that interconnects with the console preamp including, I think, the M-100.</P>


            On the Accutronics website, click on PRODUCTS, scroll down to the Type 4, which shows a photo of what it is. Click on the photo and a page will come up with an explanation of all the places in the part number.</P>

              Thanks for that. I realized based on your instructions I was on the WRONG accutronics web site. That would explain why I couldn't find it! [H]
