HAven't had a chance to cost the shipping yet they're killing me at
work right now.
But as soon as I do the wheels will be on the way.
About the shielding with steel your right about that.How about a lower
grade
stainless steel that is magnetic,I think the material cost would be offset by
less
handling and no plating or paint either.The stainless may discolor but NO
rust
and can be polished for a show model.

Re: [hammond_zone] What t402 I thinks of it :) +email

Randall Bush
 

Hey Zoners!
I want to thank Darren, our fine mate from the UK, for finding these valuable documents! As you all know, this is the issue that determines the viability of re-producing a TWG assembly. No real "work" has been done on this thing, as all of my contacts have simply been in the pen/pencil/paper/computer stage right now. All of these folks are performing this work gratis either because of their fascenation with the project or they owe me somethin' :). They all know nothing serious begins until we ascertain patent status. Thanks to Darrin (I'm uploading a four-pack of Guinness to you, mate), I now have a good place to start with the patents. I've already sent Darrin's info to my attorney who has a good patent attorney on his staff. Sometime next week, he will be in contact with the appropriate folks at H-S regarding the disposition of the patents and how many are involved. Best case scenario, but very unlikely, is the purchase of the patents. Far more possible, is a license arrangement of some type. If neither of these options work out, enough has been learned from my associates that we can produce replacement tonewheels, gears and coils VERY inexpensively. So we'll go into the parts business! Hehe. Since I've met all you lot, my Hammond work has increased dramatically and I haven't even advertised. Rather than work on whole organs (none around here), I get sent a steady stream of amps and TWGs for reconditioning. So any parts I create will be used well. No fear, mates. More fun to come!

t402...doesn't pull any punches..heh.

Its kind of irrelivent though, the original patents still stand.
Maybe it would be better to buy up the generators that are still
around, strip and rebuild those (a recon exchange maybe, that way
your always sure of stock), plus you dont have to worry about getting
a thrashing in the courts. T402 is right about copies...I think that
most would rather have a fully reconditioned Hammond TG than a
copy...if they want a copy they could buy a new B3.

One thing though...its great to see so many teaming up like this;
Raul has obviously done a lot of work on the project already, but I
realy feel that efforts would be wiser spent concentrating on the
TG's that are already out there. Starting small and having just a
couple in stock that are recon'd. I doubt there would be a problem
remanufacturing seperate parts, but out of courtesy I would still
want to get written permission from Hammond; with over 500 of us on
this list there is bound to be one or two that would be likely
customers!

The hammondzone email has ground to a halt as I am still having major
ISP problems, I can access only about 10% of the net. I posted the

As soon as I can get ISP problems resolved the hammondzone email will

Hi Chris,
I have an A-100 and I don't think I hear any key click at all. Of course, being 68, my hearing is not what it used to be, but the organ has been in the family since it was new and I don't recall any "key click" from my better hearing days. We do not have a Leslie on the A-100. Would that make the difference?

Re: [hammond_zone] 760 Distorting......help please!

Chris Clifton
 

Kevin,
If you've already tried swapping with known good crossover and amplifier,
there's not much else to try. Can you get the treble driver from the good
760? Or possibly easier, try your back panel in the good Leslie. There's
nothing in the power supply to muffle or distort the sound. The sound from
your organ is OK? Just trying to cover all the possibilities.

Hey Daz I did my adjustment yesterday and i can't believe the increase in
both volume and distortion. And you are correct with regard to the
registrations. I normally use 888800000 and this is heaven. Cut back to
666600000 and it's clean for a Whiter Shade Of Pale cleaner sound, but still
bloody loud.

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.

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?

What I think of it WAS Re: Tonewheel generators

TWIMC and FWIW here's my upfront views on this matter. I'll then shut
up.

I can't help associating this with Jurassic Park. Some things are
simply better left alone. The tonewheel was discontinued almost 30
years ago - just leave it that way. It's a piece of History which is
gone and we are still sort of selfdelusional about it. It's over,
people - just take good care of what is left about. I'd take it even
further: Those who own a piece of indeed a glorious past have the
obligation to honour and preserve it - not replicate thus
bastardizing the original concept. I fear this would incur to certain
trends that would most likely dim the aura and mystique that the real
thing still upholds. I'm not finished yet, read on...

BUT dont change a thing in it! Stick to the original concept down to
the tiniest, most insignificant washer!


To make a TG, just as a "ad on" to the
new B3, is not going to be big business,
Hardly a business at all but that's probably not the issue here...

so to finance the project, build a
"black box B3" with the TG and a replica
AO28, and make it MIDI controlled.
Priced around 2000$ it will kill all
clones on the market.
Here's how I see it.
a) Given the choice of Raul's product against a vintage console
sensibly set at the same price, I'd choose the vintage console.
b) The pro's would definitely b.1) the wealthy would have his roadies
haul the B3 around so why should they care? b.2) the others would
definitely prefer an ultralight midi-ed XB2 they could happily carry
under his arm.
c) Would I buy a brand spanking XB3, have it stripped from all its
guts (therefore voiding its warranty) to install a new generation TWG
still lacking maturity? No. Talk value for money? Nord Electro then.

That's what I think - which doenst mean I truly wish Raul & partners
the Best of Luck.

Re: [hammond_zone] Re: valves

Chris Clifton
 

Good point Ronnie,
Reminds me of an E-100 I saw a few years ago. The Chapel was only used
every other Sunday and someone forgot to turn it off after the service! Two
weeks later the mains transformer was toast and the rectifier valve (a GZ34
in this case) had become so hot at one point that the glass envelope had
softened and had a distinct bulge in one side! Fuses were rarely fitted as
standard in the older organs, if you make no other mods. a fuse or fuses to
protect the mains transformers is definitely a good idea!

a few people swear by changimg it anually.

heaviest use are the power output valves 6BQ5/EL84 and the 5U4G
rectifier,
so if you only want to replace some valves and save cost these
would be the
ones to go for.

It is a good idea to replace the 5U4 rectifier tube as it can take
out the transfomer if it goes, or you can always add a fuse to your

a few people swear by changimg it anually.
