Interesting placement of the Leslie switch, Stereo B3?

[NYCFarmboy]

I know this area is not for organs for sale, but am posting this one here as it has been modified in a really interesting way..the split swell pedals are a really neat and I would think very useful modification that as far as I know was only available on 1930's Model E's?






from the auction:




When I acquired it, I ‘finished’ what Laurens Hammond always wanted to do. Make it a STEREO B3 ! This beauty has a split matching transformer, two swell pedals – one for the lower manual the other for the upper manual. Each manual drives TWO Leslies. A ‘Tall Boy’ 31H and 147 on EACH manual with separate tremolo. One of the horrible things that happens when you put a Leslie on a Hammond is you ‘loose’ the split vibrato. You can not have vibrato on one manual and at the same time no vibrato on the other but the Leslie defeated that. It was either On or Off. This one of a kind STEREO B3 DOES allow you to have split LESLIE – and so much more. With the Doppler tremolo system of the Leslie, the STEREO effect is mind blowing. Absolutely gorgeous sound when two channels are playing together. Upper and Lower – both separate and with separate tremolo controls and volume pedals. Truly amazing sound.




This RARE Cherrywood finish Stereo B3 is fully loaded. It has the most sought after vintage Organ Mate tube reverb built it. Not one, but TWO of them. One on the lower. One on the upper with separate level controls for each that come through the Leslie horns – as it SHOULD! Along with that is has the VERY rare and ‘must have’ Kruger String Bass model 710 serial number 60442. (black box to the extreme right in the rear picture)




One very, very rare and important part is a FACTORY switcher from Don Leslie that he built for showrooms that allowed FOUR Leslies to be driven and switched from one console. I was in the retail Hammond B3 business for years and had this switcher from my store. Having sold thousands of B3 in the lifetime of our store and being one of the very first to package B3 consoles for touring groups, I have a lot of experience with Hammonds and Leslies and of course designed, built and keep this rare, one of a kind Stereo Hammond B3 in perfect working order in my personal studio here in Southern Illinois.

I've never liked Hmmonds much, but this one is amazing! Would be good in an auditorium somewhere. </p>

Let's just hope that it doesn't get bought and chopped.[8o|]</p>

Thanks for posting. I like stuff like this. Gives me some ideas for my Model E! The only thing he doesn't have is an AGO pedalboard.

Funny you should say that. I've often thought how easy it would be to split the outputs on the Model E. The inputs are already separated through the first stage in the preamplifier. Just change the 6C5/6J5 to a 6SN7, add a second output transformer and a few resistors/capacitors for the other half of the 6SN7, and Viola! That would be a fun instrument!</P>


Also, please check your inbox when you have a moment.</P>

And I can't wait to replace the preamp with a solid state one .. y'know, to save space ... for the ..</P>

My, are we funny. Perhaps this</p>

would be a suitable choppin' for all the choppers out there.[:D]

Yes NYC, I understand the purpose of it is to make it easier to carry the chopped chopper to gigs.</p>

No, I'm pretty sure it's for catching appendages afterward. </p>

Re. the stereo console: I think that mod would be pretty easy to do with most consoles. All it would take is two pre-amps and two expression pedals. Look at this picture:</p>

</p>

Don't those things on the left look like run of the mill Hi-Fi tube pre-amps? They look just like a pair of Heathkits I used to have. Hard to tell from the pic, but I wouldn't be surprised if they were. I fully intend to do this mod to a console sometime down the road, (except maybe a little tidier).

This set up has been offered a couple times in the past...bidding got up to $8700.00 last time, and the reserve hadn't been met. It is a really cool piece, though.......Heil Sound (Bob Heil),was quite a pioneer in the early days of sound reinforcement, I bet it works really well.

I'm a bit inspired here. </P>


So, what's stopping a fella from taking the vibe scanner out of a non-recyclable tone gen (or just buying one from a supply house), wiring the output of the lowermanual (or upper, whichever) to it at or near the matching transformer, and routingthe 2nd scanner'soutput back to the preamp. </P>


You could use a variable speed motor (or a two speed setup would work just as well) to drive the 2nd scanner and have it go slower than the standard rpm (whatever that is). And I would imagine a 2nd delay line would be needed also.</P>


Then, the two preamp/two lesliesteup (as is featured in this thread) could be adopted as well .. or not.</P>


I could easily fit all that suff in the lower of my '62 A-102. I have removed the power and reverb amplifiers,the reverb tank,as well as the speakers, the amps need serious rebuilding, and one of the main speakers is DOA. But there's gobs of space so adding my "vibe scanner in a box" idea would easilyfit, as well as the twin preamp deal. I would imagine it would be about the same for spinets as well as C's and A's. Tons of space [:)] ...</P>


</P>


And for the record, I very CARFULLY and with all of the respect owed to a 50 year old work of electromechanical grace .. removed the above mentioned parts and have lovingly pulled the tubes and packed the amps and speakers up to be stored. So you can put away your ~ahem~ penal system and the Spanish Inquisition is excused as well, Cardinal. [;)]</P>


So, whaddya thimk? Can a 2nd scanner/delay line work as described?</P>

Oh, I forgot for a moment there, that the E is special case. [:$]

Don't see why not, and the idea of a variable speed scanner drive motor is a good one. You'd also need to figure out how to get the second vibrato control and switch in there somewhere. </P>


With two preamplifiers, it should work very well. With a single preamplifier, you'd also need to replicate the 6AU6 amplification stage and the 1/2 12BH7 cathode follower to match impedances to drive the delay line but that shouldn't be a big deal compared with the rest of the project.</P>


Let us know how it works out!</P>
