Finally my Leslie 147 has been installed...

[Guest]

...by a tech and it sounds great with my M111.

</p>

What I notice is that the sound is too clean, glassy sounding to my years, obviously depending on drawbar registrations. I boosted up the gain on the organ's amp via the screw in the swell pedal, Leslie volume is on 5/6 but I can't crank the volume up because of the neighbours...Is there a way to get it sound a "little" more like a C3 or A100, meaning ballsier, fatter? Or because of lack of foldback the spinet sounds so different from a console?
</p>

The technician replaced the original Leslie 6550 tubes with KT88 ones (new in box from Easter Europe).He told me, after using some sort of tester, that the tubes were about to die. He also replaced a tube on the reverb amp that also tested bad.(he told me that particular tube, if bad, would pose a fire hazard)</p>

He connected the MME and Leslie switches and set up the load resistor on the Leslie to open. (somewhere I was told to set it up to 8 ohms...I' very confused)
</p>

Also, I noticed that the ramp down on the drum rotor is too fast, so I don't get a very pronounced "out of sync" effect between horn and rotor. Is there a way to make the rotor to spin slower on Chorale? (the guy adjusted the belt)</p>

Bottom line: I don't hear "sound bouncing and coming from everywhere" as some purists stated when using the real McCoy.(the Leslie is on the corner, angled at 45 degrees, 4 feet away from the organ-to my left-back panels are on except the one for the horn, which has its original deflectors, thick carpet on the floor)
</p>

Please, enlighten me.</p>

Thanks!</p>

Glad to hear you finally got it connected.</P>


I recommended ealier (a post on HC) that you set the load resistor to 16 ohms since that's what you're passing to the 147. My M100 and 147 are set this way and it seems to perform best at that setting. When set to open, my leslie was modulating amplitude - significantly. Maybe the more technical folks here could confirm if it should be set one way or another.</P>


Congrats on the install!</P>

Hi Bones: how would you define "modulating amplitude" sonically speaking? Did it make a big difference between Open and 16 Ohms when MME switch is set to Echo? Leslie only)</p>

Thanks!!</p>

modulating amplitude = rapidly changing / repeating loud to soft volume levels when smoothly increasing the organ's volume to max (expression pedal). Setting to 16 stopped this problem. I can goose the expression pedal without issue. "Echo" and "Ensemble" were effected.</P>

About your speed question:</P>


Check the pulleys on the output shaft of your Leslie motors. If you have the double pulleys and the larger one is in use, try the smaller diameter pulley. This will also slow the fast speed however. This is why I like single speed Leslie cabs (45, 47, 22h, 50, 51 etc.)fitted with a Carribean Controls 2-speed kit.You can dial in the low speed to whatever you want. I like mine set at a nice slow grind, slower than a standard slow speed on a two speed cab.</P>
