This is a great Leslie for home or gigs. Originally a model 47 but modified to a two speed (four motors, not a solid-state simulator) and rebuilt with very special features. The power amp has all new capacitors and resistors. Transformer voltages are spot-on and tubes all tested good. The crossover capacitors are also new replacements. There is also a small Hammond tube type pre-amp mounted inside, with a small and very quiet cooling fan. While this Leslie can be used as a regular 147 type/six pin hook up with your Hammond organ, you have the ability to plug the internal six pin connector from the internal pre-amp to the Leslie amp. Then plug in the separate power cord (included) and the foot/speed switch (included with cord) turn it on and you have a full size two speed Leslie that works with any typical keyboard, guitar, vocal(?) 1/4" input. Please see the back panel photo that shows the (lighted) power switch, two 1/4" inputs, power cord connection, fuse, gain adjust and speed switch cable receptacle. This cabinet has wheels, metal corner protection, angle iron bottom edge and back edge protection and two handles on each side. A great and very versatile/multi-use full size industrial strength Leslie but looks decent enough for your living room. Oh....and it sounds GREAT! Delivery not included but negotiable.
