  • Leslie 740

    Hello i am new here and i posted looking for a 740 manual and i still have yet to find one , but if anyone knows the break down of watts to each amp that would help a lot i know that it is 220 watts total . I am now putting it back together and i must say that the bottom half has been a real challenge without anything to point me in the right direction , but it is fun anyway. (he he he) Any help will be great and i am a leslie lover i have turned a 700 to a somewhat 710 added a horn and changed the crossover to make sure the right freq get to the right speaker and i have on a m3 really brought it to life in a small church and they love it more then ever now.

    Hi, welcome to the group. I am not very familiar with the 700 model series, but Captain Foldback has several near that.

        Hello again I have done a lot of research and still haven't found much on this 740 but if I can pick your thoughts on 11 pin socket diagram it looks like 3 of the 4 channels are ground connections I have to say I don't understand this without a schematic to give me a ideal as to how it works so if anyone can help me with this I will be very grateful I have put the diagram on here to see if anyone see what I see.

          That doesn't look quite right with all those pins grounded. Capt Foldback shows the 11 pin pin outs here:http://www.captain-foldback.com/Leslie_sub/pinouts.htm

          I'll ask on Vintage Organ Facebook group as I know that one guy there has a 740, one of the only two over here. He may be able to help.

                I did the pin out as the diagram shows and it works so i looked at a few other 4 channel Leslies and it shows that those 3 goes to ground so i decided to make a go at it with cation as said it works as it should so it is right after all never thought it would but i guess they know what they are doing. thanks for the feed back but if he gets back to you see if he has any ideal where i can find a manual again thanks a bunch.

                  Well I found that the pin out was not really right for the 740 the input is + going and not - going and what a different the right connections make wow is all i can say very powerful Leslie for sure now i'm able to set it up correctly and the Rotosonic is a lot better then I thought it would be handles below 100hz for a 6x9 is very impressive and the 15" woofer taking the pedal bass this 740 gets loud and a very solid sound. thanks andyg for your reply you have been a big help.
