Hello everyone, I know the last time I needed help this was the best resource I'd ever encountered on the web. I posted this on the FDP forum also just looking for various input but I'm not sure there will be anyone over there with this kind of experience. I tried to ask once before there and got no response. Then I remembered M.E.F !!! Yes!
I need to use this standard two speed Leslie speaker assembly (see photo) to build something similar to a 1960s Fender Vibratone amp. I've seen photos of that amp and it's Leslie assembly is nothing more than one of these stock units with some minimal supporting circuits and crossover.
The only thing I dont like about the fender design is the vertical plane they mount the speaker on causing it to not be as effective in a room as the old horizontal oriented speakers, in my opinion.
I'm thinking I'll need to build at a minimum some kind of power and control circuit for the Leslie with a couple of switches on the unit or at my feet to control it's speed and on/off. I also know they used a crossover circuit to feed the leslie 8-10" speaker with mids only. Not sure if I need that or not.
I'm tossing up the idea of building this as a non amplified slave speaker to a small Fender amp using the EXT speaker jack. I'm also tossing around the idea of installing it's own small amp chassis inside such as a hanging tweed deluxe or something similar. Needing advice ideas and especially details on what powers these motors, relays and assembly. It's easy enough to connect an amp to the speaker and build the cabinet but I'm just stuck on the Leslie two speed power and control. I found some semi helpful articles and photos on the web nothing complete enough to give me the info I need to build the supporting circuitry. I'm guessing a real schematic and diagram for this amp may not be available like many others. I'll keep looking.
More than anything I'm hoping for that added wisdom I usually get from this place. Nothing beats experience. Thanks again for your help in advance. And thanks for the help on my last project (BFPR) which has been working FLAWLESSLY for months.
