Re: [hammond_zone] CV refinishing/Trek II question
Julian,
I can help you out with the CV/Trek II and a little on the refinishing question. I have a Trek II unit on my BV and it sounds great. You can install it, it's fairly simple. Contact me if you have problems and I can walk you through it. I wouldn't worry about the resale value to refinish it if it would look better to you. CV/BVs sound great but people just want the C3 B3 for, I guess, nostagia reasons and some swear it is the ONLY organ for them but if you can get basically the same result with a CV, so install the Trek II and you will be amazed! A CV/BV with percussion sounds better to me as I have had two B3s and either one didn't sound as good. I had my BV walnut color matched to my Leslie 122 and as far as the resale, it's worth a million dollars to me as I will probably keep this one in my living room. Hope this helps...Eddie From: "Julian St Martin" <julianstmartin@...> _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: |

Re: [hammond_zone] two schematic questions
Richard B. Ahlvin
Cant answer #1
(2) Not having a Hammond in front of me, it makes sense that the vibratoline caps are non-polarized, in spite of the curved+straight plate on themarking power supply filter cap + sides (although it's obvious from the circuits)and when I learned electronics, one used parallel plates for non-polarizedcaps. Capacitors are often represented schematically with a straight and a curved line. The curved line represents the outside foil. In certain applications additional shielding can be accomplished by hooking the outside foil to ground. I don't know if this was actually done on the Hammond vibrato line boxes, but it was always a good idea. Many capacitors are marked with a line on one end which is the outside foil connection. The same schematic symbol (one straight, one curved line) is used for polarized capacitors in lieu of marking one side with a "+" symbol. I have seen both used together. R.Ahlvin |

Actually, he also said he can bring it down 2 octaves if I want it at 32-foot pitch. I know nothing about how this organ works. How is it possible to change the pitch of a stop like that? The stops on the G-100 are created by adding the various available harmonics together using fixed resistors. It can be thought of as fixed drawbar combinations. To change a stop, it is only necessary to add, delete, or change the resistors for that stop. R. Ahlvin |

Hypothetically speaking of course, is it possible to change the speed? I know the vibrato is belt driven on the G-100 so it is easy to change the speed by changing the size of the drive or driven pulleys. For tremolo, there is a transparent patterened wheel that modulates a light source which is picked up by photocells. It is driven by a clock motor. I don't remember whether it was belt driven or attached directoy to the motor. If belt driven, it would be easy to change too. If it is directly driven, then one could power the motor with a variable frequency oscillator to get other speeds. Such a circuit would not be hard to build as a clock motor uses very little power.

Re: [hammond_zone] tonewheel resurrection update
Raul, a LONG time ago when I was in Jr. High we took a family vacation to
Durango and went to some kind of cowboy place out from the city.... Cowboy music (no Hammonds however) and a stage show. Is it still there? I had a great time... We got together with a family we knew from when we lived in Wisconsin. They had a couple of boys my age and all I remember is that we were wild and made our mothers insane. George |

Re: Tonewheel generators
Jens Aage Andersen
It seems that Raul is going to do it,
with help from fellow zoners. But is the purpose to make an exact copy of the original, or is it enough to make the sound right? If the sound is the main issue, maybe it would be a lot easier to use step or server motors to run the tone wheels, one for every speed needed, instead of all the gears and shafts. I am sure there are experts on the zone that can answer that. To make a TG, just as a "ad on" to the new B3, is not going to be big business, 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. Jens Aage Andersen Denmark |

Re: [hammond_zone] a-100/47 hookup !!!!!!

Those things that say1,000VDC are the capacitors used to suppress electrical switching noise on the relay contacts. When they fail they usually go short circuit, causing the relevant set of motors to run all the time, if they go open circuit you will have a loud "pop" through the speakers, (and on any nearby radio or HI-FI) when you change speed. If they're cracked as you say, then replacement would be a good idea. They are 0.1 ???F 1,000 volt rating, I usually replace these with parts with an X2 rating specifically designed for mains suppression use, I'm not sure about USA availability of these. The power supply current to a Leslie is about 1 amp. (2 amps USA/ 117 volt models). Light gauge wire will do here but make sure the insulation is suitable for mains use.

two schematic questions
(1) I've found several copies of the AO-28 schematic on the net, but I
haven't run into any copies of the AO-28 wiring diagram. I checked the Hammond FAQ, Captain Foldback's site, and Hammond Zone. Did I miss it ? Is there such a critter out there? It would be helpful for rebuilding my AO-28. (2) Not having a Hammond in front of me, it makes sense that the vibrato line caps are non-polarized, in spite of the curved+straight plate on the schematic... Hammond schematics don't seem to be consistent even in marking power supply filter cap + sides (although it's obvious from the circuits) and when I learned electronics, one used parallel plates for non-polarized caps. Am I right ? Doug |

Raul,
I'm not questioning your proven skills mate don't get me wrong - I have a pretty good idea what league you're playing in and there aren't that many like you around and I cherish that a lot. My outspoken concern has all to do with... money! Plain and simple! The stuff that make the planet whirl happily one day at a time. I mean thank God (mmm nice touch for a diehard atheist like me... ) someone's finally grabbing the bull by the horns and testicles to come forward with such a great project like yours (technically it's a full orgasm - AAAAAaaahhh uuuh ...) HOWEVER - devil's advocate - I'd very seriously ponder its costeffectiveness. In other words do you have a decent portfolio of customers, is there a sales forecast say for the next 3 months as well as for the next 2 years enough at least to cover running costs? What about tech support? Say I've inherited my late auntie's B3 but strangely enough the mice chewed the TG down to little crumbs here and there - how much would cost me one of your TG's? How much do you think people is prepared to pay for something technically *apparently* one step backwards? Raul dont mean to put you off - I back you up 101% HOWEVER I'd be very very very skeptical about the whole prospect along the time axis. Do some marketing research before jumping head on. Wait for the downturn to wear off. Things are still a bit flaky.
