Re: X-66 Trouble shooting Help
Bob,? I just wrote to Paco to try to speed up your joining Hammond X66 club. You might try later to see if you are accepted. When writing to him keep it? plain with no big words as he speaks
Spanish and very little English.? His repair mans? name is Jorge and he is good on X66s I could not give him your email address as they cut off the last part in your previous message. I assume it is either yahoo or Hotmail but I don't know.? If I hear back I will let you know. ´³¾±³¾...¡... |

Hi hammond_zone peeps, It has very odd strings, that look like the wire is coiled -- I spent a while online searching, didn't come up with any real information, couldn't find a manual or service manual -- The person needs to find some replacement strings, as a handful of strings are missing -- They report that the instrument works, all notes produce tones, just the strings need replacing. Any info?? any thoughts on where I might search for info? Anyhow, I thought if any ones might know about this, perhaps you peeps might!? Thanks for any info, Gesine |

Re: X-66 Trouble shooting Help
Hey Jim -
I am assuming that my divider circuits are working because I do have proper tones on each and every key.? What I don't know is the amplitude of the signal from the TG feeding them.? I may be wrong in this assumption, but shouldn't the output of the TG remain constant regardless of age?? Rotating wheel, magnetic field, seems impervious to age in my book (unlike myself).
Can you or anyone answer that question?
I guess looking at the proportional keyers is the next step after the TG and as you said the Flute filters.
I'm gonna get a scope and do some checking of wave forms and P-P outputs.? As I said, I'm new to this, but there is a lot of winter left here so it will keep my mind busy.? Better then doing crossword puzzles.
Take care,
Bob
PS:? If anyone is looking for a good investment, buy stock in Captain Morgan Rum. . .there may be a spike in sales depending how this goes!

Re: X-66 Trouble shooting Help
Well it's a start but as they say a journey of a million miles begins with a single step.? Well that's where I am. . .step 1.?
Still looking for input regarding low level signal from? TG and lack of function of drawbars and tabs.? Any input from anyone is appreciated.
Thanks,
Bbo

Re: X-66 Trouble shooting Help
Jim - I've isolated the weird motor like noise. It's coming from the TAB Voice Channel.? Drawbar channel A and Drawbar channel B are still very weak and volume is not changed by use of the expression peddle.
FYI
Bob

Re: X-66 Trouble shooting Help
Jim - Thanks for the follow-up.
I do have a complete set of schematics and I'm slowly working through them.? I just bought the X66 two weeks ago so this is all new to me.?
I did play around with the scanner and it did not change anything.?
Also I did put in a request to register with the X66 club three weeks ago and as of this date, my membership has not been approved.?
I am going to try and isolate each of the output channels and see the noise is on all of them or just some.? Work backwards if there is a difference.
Thanks for your continued support.
Bob

Re: X-66 Trouble shooting Help
Bob,, I will have to see if I still have a service manual out in the garage, in the mean time their is a web site in Mexico where Paco De La Rosa has the X66 Hammond club, he has a great service man that is outstanding on the X66. He has several X66s and his service man could probably give you some solutions to your problems. ? Type in Hammond X66 club and look for him. You can also look on youtube for Paco at the X66,? mention my name to him and he will probably help you..
mean while I make a trip to the garage.? Jim McComis in Ohio |

Re: X-66 Trouble shooting Help
Hey Jim -
Thanks for your input.? Did what you said with the exception of the BusBar.? I couldn't find any reference to them on the X-66 so don't think it has them.? I could be wrong,.? I know my other Hammonds do.? No change inn the organ performance or lack thereof.
Additional note on the noise:? It sounds like a motor spinning up and them stabilizing.? Any chance the drive motor on the Tonewheel generator could be causing a problem?? This organ doesn't have a grounded plug.? Should I run a ground to the chassis?
Thanks again Jim.
Bob

Push all resets on and off to see if it changes, do the tabs the same way this may take several times. On the left side, try holding down the cancel key while rapidly pushing each preset about 20 times as fast as you can, you are looking for some change in tones, next ? try shifting the busbars, also it sounds like it could be in the filter section.

Re: X-66 Trouble shooting Help
OK, that's cool just trying to cut down on messages floating around.
So this is my problem.? I have an X-66.? All power supply DC voltages are right at spec.? Tonewheel Generator (TG) sounds and runs great.? When you unit is turned on, faint notes can be heard from all keys and appear to be at proper frequencies.? But the tones do not change with any changes in drawbars or tabs.? Also there is a loud background noise which when the expression peddle is advanced gets very loud. Switched tone cabinets so those are not the problem. Those are the facts as of this time.? Input of any nature is appreciated. |

Re: X-66 Question
I am replacing all the brittle lamp cord line voltage wiring in the console.? I ran across one wire that goes from the AUX Line voltage plug at the base of the organ, up the chrome tubes and then disappears under the scanner module.? Does anyone know where it goes? I can't find the wire on? a schematic.? Do I have to remove the entire scanner module to replace it?? Any help would be appreciated.
Thanks. ? |
