T500 - Percussion 'change'!

[Guest]

Hi, I'm a new member.</P>


Have two T500 Hammond's and two H100 Hammond's.</P>


I have made a better 'Keyclick' by following Carsten Meyers T-Series Mod's.</P>


And I also 'changed' the BANJO and CHIMES Percussion.</P>


On the Banjo perc.I removed the 'fixed resistors' wich made the BANJO and</P>


changed it to a Third Harmonic 2-2/3' + 1'.</P>


Soldered a 33K resistor to the 2-2/3' voice and a 56K resistor to the 1' voice and</P>


top of the resistors to their common out-pin.</P>


And I also changed the CHIMES Perc. to a Third Harmonic 2-2/3',by removing the</P>


'fixed resistors' for the CHIMES and thensoldered a 33K to the 2-2/3' voice.</P>


And I also made a short decay on the 'new changed' Third Harmonic perc. (Chimes Tab).</P>


Both percussions together with Carsten Meyer's Mods on 'Keyclick' makes my</P>


T500' sound very good!</P>


Keep the Hammond's sounding good!</P>


Best wishes from Carsten P.</P>

Evening squire!</P>


I'm a complete T-500 mod nut. Have you got a recording of the extrapercussion on those last tabs?</P>


The T responds very well to being modified, eh?</P>


Have you had a look at the other T threads to see what kind of things we've had a bash at? </P>


Let me know if you're interested in any other mods.</P>


I'm keen to hear this new mod for my own improvement project!</P>

Re: T500 - Percussion 'change'!

Hi, I am very much impressed by the sound of my old H-100, srtarted to completely rewire the percussion tabs so that I now have the joy of six harmonics, independantly switchable. I am now working out how to be able to control the percussion length with the (useless) reiterate pot.If someone can give me a hint on this I will be very grateful! Otherwise I have to work it all out by myself. I expect I have to do some trick with the capacitor in the percussion control circuit.Maybe have the variable resistor parrallell to it.

G'day propeet!</p>

Carsten, (above) made quite a few changes to his T-500, as did I, the place we both started out were on Carsten Meyer's pages</p>

athttp://keyboardpartner.de/hammond/t-modifications.htmsome of those mods may be convertible to the H.</p>

Mr Meyer promised a series of H mods athttp://keyboardpartner.de/hammond/h-modifications.htmbut evidently got too busy with day to day life and work. Maybe one day he'll get back to it.</p>

Let us know how you get on, because mods like these are important for users like yourself looking for this very information.</p>

I can discuss similarities and differences with you, its possible my T-500 work may be similar.</p>

The best resolution h100 diagrams are here:</p>

though check outhttp://www.captain-foldback.com/Hamm...schematics.zip</p>

as well.</p>

Look at Carsten Meyer's percussion length mod and tell me if it looks at all similar to what you have...</p>

Cheers!</p>
