Im guessing peavey (it was one of 2 unmarked and mismatched drivers in a peavey 2x15 cab).
 
its one of the cheapest looking drivers Ive ever seen.

I had to do an emergency repair on a Leslie 760 last week for a band going to Spain to record their first album, the lower rotor was behaving but the top rotor only turned when fast speed is selected, the drive is wonderfully simple, there are two motors piggybacked with a wheel in between. The fault was quickly traced to a transistor that fires a reed relay that fires a triac which turned the slow motor on and off.
The client (panicking) waited with it whilst I worked on it so I was only able to get a couple of photos when he went to the bog, they are still in the camera which is in a box under a ton of other boxes waiting to move into the new workshop in Wimbledon SW17 (near the stadium, plug plug), I will be moved in a couple of days, the beer fridge goes in on Monday after that I will start unpacking and will be able to post the pictures if anyone is interested.

Any thoughts on micing one of these for live use?

I've may have to do it in the near future. I don't have access to an exotic range of mics, would a 57 on the top and a kick mic on the bass work OK, or is there a better solution? Also, would it be worthwhile using 2 mics on each, one either side to better reproduce that 'swirling' sound, or would that be a waste of effort?

Cheers

Well, yes. The best possible way of micing one of these is by using 4 microphones. I know, it's an expensive jobby, but take 2 mics like the SM57 for the HF, one left and one right of the rotating HF and connect it to a stereo channel! Do the same for the LF, but use a different microphone which has more low-end extension. This will give you the best results, without loosing any quality of the effect itself.
Best regards,
Teun.

Nothing quite like the sound of a hammond organ with leslies. We get them toured in from time to time and rarely need to mic them up, especial if its a pair of leslies. They are just so darn loud! It's also great to see equipment with moving parts on stage.
Sound is analogue, get over it!

Baker in Croydon? Next door to Saxon in the late 70's Don't think that's a Baker driver, much cruder cast chasis IIRC.
Baker used to quote frequency response in CPS, ahh the good old days..
 
Edit. Wow, just Googled them, this was the correct address
 
Surley not still there?

I usually mike the top part with pair of SM57, MD421 or MD441.Not necessarily from the opposite sides but from two sides, so that the mikes are 90 degrees from each other. Don't forget to pan these L&R

Bottom part could be done with only one mike, if two mikes are out of question, MD421 works nicely. I would guess Heil PR40 would be properly nice there too.

i have a coppy in the workshop at the moment the only difrence seems to be a polystryen bass scoop and mosfet amp a part from that the moters are the same it even has a simuler fault i have replaced the triacks and am thinking of replacing the relays but i will check the transistors first
i am looking for a 4 ohm 12" speaker for it any sugestions

I love them things,cant beat that authentic Hammond sound through a Leslie .
The mains have to be well stable cos with frequency fluctuation the speed of rotation varies, i read somewhere with a naff generator can sound bad. Love the valve kt88 valve amp.Thumbs Up
LET THE BASS ROLL LIKE THUNDER
& THE TOPS LIKE LIGHTNING.....

The 760 that was in for repair was, sadly, only with me for less than an hour. I did have time for a quick look round though. Yes, the synchronous motors will be unchuffed  with frequency variations but the horn assembly spins so fast, 4 or 500 rpm full bore, I'm not sure that it would be overly displeased. (would make a mess of either your fingers or a mic)
The one I had in had transistor amplifiers, circa 1974 I would guess, but huge, five feet high and three wide.
The motor control was either fast motor on, fast motor off, slow motor on, slow motor off so shouldn't be hard to find out why it isn't turning.
I will try to locate my camera in the next day or two.

As these things are not very hi-fi, having a restricted frequency range and usually being rather noisy, you don't need exotic mics. There are two things to be aware of.
First, the rotating horns and reflectors cause a lot of air disturbance, so your mics need good popshields.
Second, much of the characteristic sound is due to the phasing effect as the hf horns rotate, and to reproduce it requires a stereo pair of mics on the top section. Either one each side pointing towards the middle, or a proper crossed pair - whatever best gives the sound you want. A pair of general puropse dynamics is best,  SM57's or whatever is to hand. I have a pair of old EV 408's which work well because they have swivel mounts and can be positioned where they don't get in the way.

A lot of people expect to use a specialist LF mic, say a D112 or whatever, on the low end (only one is needed here). However you usually end up rolling off a lot of LF noise and rumble which defeats the purpose. I find an SM58 is adequate - it has a good pop filter and not too much LF, and survives being kicked when people stumble into it in the dark.

A Hammond played through a Leslie is one of my favourite sounds...

I did sound for a band who had one of these last summer. The keyboard player arrived in one van, the rest of the band in another. It was good fun lifting the hammond up onto the stage (3ft high, no ramp), made getting my amp rack up there seem easy.

I went for a pair of 57s left and right just inside the top section, panned left and right, and an ATM25 for the low section. I think that went around the back of the cab pointing into an opening. When he started playing it I soon understood why he bothers taking it out on the road- I've never heard anything quite like it, really warm sound with a very subtle un-cleaness about it. The top end was beautifull and really sits well in a mix, was fascinating to watch as the speeds change too.

I doubt I'll see another one anytime soon.
Blahblahblah
