  • Leslie 710?

    Still searching for a Leslie upgrade from my 825 model I currently have hooked up to my A-100 and stumbled on oneof these 710models (been looking for a 760). From what I hear it's supposed to be similar to the 760 model butin a wood cabinet with a different bottom speaker setup. Can anyone hear comment on the bottom speaker difference? I already have a Combo Preamp pedal to hook up the 9-pin cable to the speaker. I'm mainly wondering how the difference in the bottom speaker affects the overall sound. Also, any idea on what one of these might be worth?

    The 710 is very different to the 760.</p>

    710 is a two channel cabinet. The stationary channel has a 15" and two 6x9". The rotary channel has the usual treble driver and horns but the lower frequencies go through a Rotosonic drum, with just a single 6x9" speaker. This means that the rotary channel is incapable of handling bass and really low frequencies. You have to install a crossover in the 710 that diverts the bass and low frequencies into the stationary channel. It's a well documented procedure. Do a search here or on the Hammondzone Yahoo group for details.</p>

    You should be aware, however, that the wind up/down times of the Rotosonic are much, much longer than the lower rotor of the 760 (or the rotor in your 825). The treble horns behave normally, like a 760 or 147, and this masks things a little. The tremolo effect from the Rotosonic is also much heavier - it was designed to emulate a theatre organ tremulant. These two facts, plus the need to modifiy the cabinet, put many people off. However, 710's are very cheap for a leslie and that's attractive to some players.</p>

    I think the 710 suits the LSI Hammonds like the Concorde, Elegante etc very well, but I'm not so keen on the sound it makes on a tonewheel Hammond. I had one on my T500, but much preferred the 'normal' leslies like the 122, 145, 147 and 760. If I were you, I'd hold on for a 760 or 770. They are quite common here in the UK and the gigging 'Pro-Line' versions can be reasonably priced. I've also seen some 900's and 910's go for reasonable amounts.</p>

      The crossover that Andy mentioned is from trekII and is called the LCO1A The included instructions make it easy enough for a child to do. I fitted one in my 710 the other day.</P>


      I can't comment on the sound on the 710 yet, I am still waiting for a replacement 9 pin plug from Goff!</P>


      I intend to do the conversion on the lower rotor eventually. This will make it a 770 which is the furniture quality version of the 760. Captain Foldbacks Leslie page lists all Leslies for comparison.</P>


      The hammondwiki pages have an explanation of the conversion procedure by Mike Casino.</P>

        Thanks for the input guys, I think I'm going to pass on this model. I did find a 760 on craigslist though; the guy is asking $700 and it includes the preamp pedal. Does this sound like a good deal? Not enough of these sell on Ebay for me to guage what a decent price is.

          I finally got the 710 wired up to my T202today (I have not ever used the 710 in the time I have had her). Yes that roto sonic was rather a shock! I think it is still slowing down as I write!</P>


          One thing I noticed is that the plug keeps popping off of the merotac. Is this a known problem? I have lightly lubricated the top of the merotac to try and stop the plug catching so much.</P>


          Cheers</P>

            Of course when wiring direct from a T200, you can avoid the need for a crossover in the leslie. You run the signal from one of the 12" speakers into the straight channel on the 710 and just the signal from the leslie's 8" to the rotary in the 710. The crossover in the T already diverts the bass to the straight speakers.</p>

            I've not known the contact popping off a Mercotac before and I've 'abused' quite a few 710's, 715's and 415's when lugging them around over the years. The Mercotacs have been very resilient.</p>

            Anyway, have fun with it. Don't forget to turn the 710 to fast tonight before you go to bed. It might be at full speed by the morning! :D</p>

              Tonewheel,did you check if the Mercotac is stuck?Hold the drum still and try to turn the stem at the topwhere the contact attaches, there should be little resistance. That's usually why they throw the contact off. Sometimes you can get them to turn again, i've left them set in WD40 overnight and sometimes that'll help it. For whatever reason, the black colored ones always gave me more trouble than the polished ones.

                Yes thanks Davethe merotacseemed to be grabbing and a shot of WD40 seemed to do the trick, The upper fast motor wasn't working either even though I rebuilt it a month ago. I added more oil andhung the stack back in the wrong way round by mistake and it works fine! If I turn it back the other way it stops working again?!</P>


                Happy days!</P>

                  I'm sorry to revive an old thread, but how much is a Leslie 710 worth?

                    Hi Andy,

                    Would you be so kind as to provide additional detail on your Leslie 710 rewiring? "Of course when wiring direct from a T200, you can avoid the need for a crossover in the leslie. You run the signal from one of the 12" speakers into the straight channel on the 710 and just the signal from the leslie's 8" to the rotary in the 710. The crossover in the T already diverts the bass to the straight speakers."

                    Does this mean you remove the wire from the 12" speaker and attach them to the rotary horn wire?

                    Best!

                      Yes, I have an A-100 connected to 2 Leslie 710s with the Hammond kit I'm very happy with the sound and setup. Yes, the Rotosonic is slow so I just rolled off some of the volume to that channel so as to be less noticeable. Obtained Leslie a 710 for $250 and had to buy about $50 worth of parts.
