http://www.fishorgans.com/leslie_kits/7953_kit.pdf is some info on hooking up to a 705 or 720, the units are similar. I had the 720 hooked up to a Conn 640 years ago, then an Allen then a Viscount. Do you have a tech to do the hook up or will you do it? I've done it before, with the schematic it's not too bad. The connector kit, which is $299 now, had an 'almost fried' resistor on the channel used for 4 channel organs. It works fine though you can fix it for $3 at Radio Shack. That's why I'm selling it cheap., The 705 hasn't been fired up before, still crated, so shouldn't be a prob. Lots of Leslie people on the web with good info on how to oil the rotor etc. I'm including the service manual for the 720 which covers maintence.
With 2 of them going you'll get quite a nice sound, they both do fast and slow.
