Re: [hammond_zone] Leslie won't slow down

Nick Renich
 

Hey Ron i switched the two 12AU7's over, but still have fast speed only. The
half moon is smashed-completely disintegrated. There is absolutely NO
bakelite, just the metal switch and wiring which appear to still work, but
do not slow the Leslie down. Just the same, thanks for your advice.

Re: [hammond_zone]Re:Tonewheel generators

Ron Bell
 

I am wondering what material should be used for the end plates.
The originals were cadmium plated steel or zinc plated steel, this leads to
alot of dendrite build up though., maybe if they were sprayed with krylon. I
know that the steel generator has to be grounde VERY well or else you will
get a lot of crosstalk, if the generator was made of a less conductine
material would the shielding properties eliminate enough crosstalk?

Re: [hammond_zone] Screw

Ron Bell
 

You dont have to remove the screws, just the little round plug. It is a
variabl capacitor not a volume controll, turn it all the way clockwise, this
is the quietest setting, do not turn it more than two turns counter
clockwise. If you screw it fight out it is a big pain to get it back in. And
like I have already posted not to much overdrive or you will toast your V-21
and these are no longer made although I have heard the 100w ferro-fluid
driver from Ham-Suz is a good replacement and can stand up to a little more
overdrive.
Cheers
Ronnie

Mounted on the centre of the pre-amp is a small rectangular aluminium box
about 4 inches by 3 inches. Remove the screws to reveal the volume
control.
At the top is a small slotted screw which you turn left to increase
distortion or right to decrease it. Takes about 1 minute and the organ
sounds like heaven. Actually it already sounded like heaven.

Brian there is a small aluminium box at the centre of the organ pre-amp.
This box is about 4 inches by 3 inches. Remove the cover to view the volume
control mechanism. At the top is a small slotted screw which you turn left
to increase growl or turn right for a clean sound.

if any of you have ever heard the sound of a large pipe organ, playing the Widor toccata, on full organ, you know what that rumble feels like. There's nothing like the sound of a 'contra bombard 32' beneath the full organ..........

Re: [hammond_zone] Re: Tonewheel generators

Randall Bush
 

Thanks, Old Guy. Actually, I was thinking the opposite. The steel plates effectively shield any magnetic flux from one cavity from migrating into it's neighboor. Generally, the crosstalk is the unavoidable consequence of having all those unloaded outputs run into the tightly woven wiring harness. It's actually amazing that there's not more of it.

Re: [hammond_zone] Tonewheel generators

 

Laddie:

This should have read :

"All interested members "

But to your question
any member of this group who ventures inti this project no matter what the outcome should at least wind up with a working
"Halapieno Tone Wheel Generator" ( HPTWG )
Of course if that sounds good to Randy.

It really might be fun to make tone-wheel systems, but it would seem that it should be a business with the
members as stockholders. Whatever, there will come some "ownership." Because there are potentially
more who would be interested, it is adviseable to create a corporation. It is not too expensive to do this in Florida.
It is a "corporate friendly" state. I don't see why the entire system could not be laser driven in its basic design.

The wheels are machined as are the gears,brass hubs and steel
shafts.The
bakelite gears look to be pressed or stamped,but may also be machined for
concentricity.The dividers are stamped out in one piece as are the horizontal
supports
with all the alignment nitches.the bushings are Oillite Bronze and are turned
parts.
All can be duplicated with the right tooling but the cost would be up
there.
Would it be worth it?HECK YES! Please respond Imight be interested in

Re: [hammond_zone] Screw

daz
 

Hi Bob,

(snipped from previous mail)

I have used the following procedure myself in the past to produce excellent
results. I was shown this procedure by a friend of mine who hired his C-3
to Keith Emerson when he came to the UK a few years ago. Keith liked it so
much he wanted to buy it, Dave said NO WAY! She is my baby.

I wrote the procedure down for future reference:-

It works on the following organs with the AO-28 amp

B-3
C-3
RT-3
A-100
M-3

Firstly select the A# (console models) key on the upper manual, set the
drawbars to 80 8808 008. Expression pedal fully depressed. Turn vibrato
and percussion OFF.

If you use the pedals pull out the 16' to position 8.

The preamp drive level is set by adjusting the trimmer capacitor that is
behind a removable plug on the cover of the box containing the swell
capacitor. The preamp should be set to fully clockwise to start with.

Turn all the Leslie controls (volume) full up.

This next step requires two people:

One person should play a full 5 finger chord in the centre of the upper
manual, and the bottom C of the pedals.

The second person should now begin turning the trimmer counter clockwise NO
MORE THAN ONE TURN. The organ should now be getting louder but not yet
distorting. Turn further counter clockwise slowly until distortion starts.

For the real dirty Hammond growl the final setting should be 1/8th of a turn
more than the point where it starts to distort.

DO NOT INCREASE TOO MUCH IT WILL CAUSE PROBLEMS! Mainly with overheating of
the drivers.

The final setting should be approximately 1-1.5 turns open on most organs.

Now the test!

If you have adjusted for maximum distortion at max volume, the distortion
can be reduced by pushing in the drawbars slightly. The result should then
be very clean sound but still very loud.

When complete you will have distortion on demand by the drawbar levels!! No
need for add-ons.

Organs with the Trek-11 Preamp should be adjusted in the same way, but the
drive level is adjusted with the volume pot attached to the expression pedal
control arm. Simply loosen the screw and use a small screwdriver to turn
the pot within the arm - DO NOT REMOVE THE ARM - all other adjustments are
the same.

Now sit down, play and bask in the nasty growling beast of a sound you have
just created!

HTH

Daz.

Re: [hammond_zone] valves

daz
 

Who told you that valves have to be replaced every 2-3 years? This is
b**l*h*t!!

There was a guy on the TV the other week in the UK who has a huge store of
over 30,000 valves, he re-furbishes old valve radios and said that he has
only used a handful of his valves as they tend to last indefinitely. The
store, which is very rarely used contains almost every valve ever made! I
watched with baited breath with pen and paper ready to the end of the show
and he wasn't even in the credits!! So there is a very knowledgeable guy
out there with an indefinite supply of valves that I can't find! I have
phoned up Sky TV and they can't give out personal information. Did anyone
else see it, it was about inventions on the Discovery channel. They were
making a crystal set, and this guy was demonstrating old radios.

Hi,

I went to take a look to the valves in my L100 today. Whit help of the age
determinationlist is was able to find out that the organ as well as all the
tubes were manufactured in 1971. All the tubes are original. This means they
are +30 years old. I've always herd that valves need to be replaced about
every 2-3v years. So maybe this will be a good moment to change my valves!
But will the sound differ from the current sound(How?) And which tubes MUST
be replaced and which NOT necesserily?
I read a million time not to take the chinise tubes so I won't take them!

Peter Hayward was one of them, better pianist than organist. He did all the

Harry Stoneham did the Parkinson Show and wrote the theme tune.

Jeff,
The Hockey m,usic we refer to would be something bery similar to this.
A very, very brassy sounding organ with great depth of the vibrato and
tremolo.
Don't know how old you are, but think back to the days of General Hospital.
Lets say through the sixties. The background music was a Hammond in the
studios. It';s sound was very brassy and had a severe depth in vibrato as
well as tremolo. The depth of these modulations was so great at one time it
would'nt even sound like an A minor chord. Just pulsating white noise. But
when the soap got to a romantic part, no distortion and a simple full organ
sound that seemed to rise in volume as the soap neared the end. At the very
end , the chord would be held and the organist would quickly lower the
volume
on the expression pedal and then once more at the cresendo bring it quickly
back up to full volume , almost to distortion, and at the same time with the
left hand , bring the 4', 2', 1', 1/2 drawbars all the way out.
Such, I always thought they were trying to imitate a theatre organ on a
Hammond.
Lets not forget the game show background music about that time frame as
well.
Let's make a deal show included that brassy sound, with a player with some
darn fast footwork on the bass pedals.
Ok, someone help me out on this one. Who were those keyboardists?
Dang good job, I thought.

Hello All!

I was hoping you might have some ideas on distortion I'm getting through my
760!

So far, I have tried swapping the back plate amp assembly, from a known 760,
but to no avail....the sound remains muffled/distorted.

Could the power supply assembly contain the fault, or perhaps a driver is
blown!!??

I have a service manual and a simple multimeter......
and am happy to 'give it a go'

Any help gratefully received
