For an example, I will *assume* your magnets are all 90 ohm ones ( that's what I see most = of ,so far, in my searches for parts anyway) What you have to do is multiply the number of ranks that can ever play at the same time by , say, 12 ( will you ever play more than 10 notes, plus 2 feet on pedals, unless your hands have 11 fingers?:-) Divide the 90 ohms by this total number of magnets that could be "on" at once. So, for a 10 rank organ, this would work out to 120 magnets, or 3/4 of = one ohm. Pretty low impedance, a 12V power suply will be pushing 16 amps into this --- and that doesnt include any of the console and controller stuff, etc., which needs power. I have no idea about that amount since every system is different -- and I have *very little* experience yet here! ! But the upshot is that you want to get = the BIGGEST HONKING 13.8 volt *REGULATED* power supply you can find! ....especially if some of your magnets are lower than 90 ohm ones!   I recommend the ASTRON RS-50 or the RS-70; these are their biggest, and I use an RS50 in a 6 foot rack full of amateur radio transmitters and repeaters which I run here, and it is a good unit, I have it in continuous duty service, 24/7... ( the RS50 is rated at 37A CONTINUOUS, but the full 50 for intermittent duty, for which I think an organ will qualify)   One good point here ---- the cost of the larger supply is not too bad; their 12 amp unit is around 120 dollars, but the 50 amp'er can be had = for around 260 or 270, at least as of last year.   BTW, the RS50 is a standard 19 inch rack mountable unit, 5 inches high. Not too big, and looks nice enuff to have out in the open, sorta looks like a stereo power amp with the 2 meters on it -- but it weighs a ton! Best of all, the Astrons are well regulated, your voltage will not drop more than about 50 millivolts under load until you are right near the max rating.     Harry Chase           .. ----- Original Message ----- From: danielwh <danielwh@ns.sympatico.ca> To: Residence Organ List <DIYAPASON-L@pipechat.org> Sent: Thursday, February 13, 2003 9:49 PM Subject: Re: [Residence Organs] Problems and solutions     > What kind of Astron rectifier would I need, what size, > My Organ has roughly 100 magnets in action with another 58 to go+ another > rank besides in the future > Magnets range from Casavant EP magnet style to Kimber Allen, to = Peterson > Danielwh > > > --- > Outgoing mail is certified Virus Free. > Checked by AVG anti-virus system (http://www.grisoft.com). > Version: 6.0.449 / Virus Database: 251 - Release Date: 1/27/2003 > > > DIYAPASON-L: a Discussion list for owners and builders of their own > Residence Pipe Organs. > HOMEPAGE : http://www.diyapason.pipechat.org > List: mailto:DIYAPASON-L@pipechat.org > Administration: mailto:owner-DIYAPASON@pipechat.org > >

OK lets say you have diodes in both chest and things worked until you added the offset chest. That = may indicate the polarity of the diodes in the added chest may be connected backward or reversed from what they are in the other chest????????   Russ

This can quickly cause the current requirements to increase! If you turn on Swell-16 and Swell-4 and lay all your fingers on the keyboard you'll be firing more than 10 magnets!

Richard did mention sub and super couplers. My mistake!   As for answering your other question, like Russ I was puzzled by the use of the phrase 'resistor diode'.   When I acquired my first (!!!) used organ the cable from console to chests had already been cut. One of the first things I did was to use a voltmeter and continuity tester (battery and bulb) to draw up a schematic of all the circuits so I had a good understanding of how things ( I thought) worked. I did the same on the chest side. Even though I'm not planning on hooking up the organ in the same way I learned a lot from the excercise. The time wasn't wasted, it *is* a hobby after all. I've had hands on experience (i.e. I've been in the guts) of two consoles now. If you want to know how a small Kimball console without a combination action is wired I'm your man. But as a hobbyist (and I suspect the majority of the folks on this list are in that category) my sphere of knowlege is limited. I try and help when I can. I am personally indebted to the 'pros' on this list ( Larry, Art, Richard, et al) who find the time to help us amateurs.   I find it useful to walk away from my project when I get stumped. (Fortunately I have so many projects going that I'm never at a loss for something to work on, but that's another problem :-)). Getting a fresh perspective on things is sometimes all I need to get a handle on what's in my way.   Best of luck with your Residence Organ Project and please don't get too discouraged.

If that's the case, have you reversed the polarity of the power supply? Doing this will make the diodes a short across the magnet, and it then won't work - and will also probably burn out the diode!   Just a thought.   Every Blessing   Tony ----- Original Message ----- From: "danielwh" <danielwh@ns.sympatico.ca> To: "Residence Organ List" <DIYAPASON-L@pipechat.org> Sent: Thursday, February 13, 2003 9:14 PM Subject: [Residence Organs] solved one probem, now another,     | I am using a 50 year old rectifier to power my magnets | I solved the problem with the earlier mentioned, Stupid me , should = have | thought of the need for adding switching for each rank added to a = contact | rail. | Anyways I have added one and the next things I add I will be doing the same | for each | Today I ran into a strange problem | Of a direct electric Mechanical windchest, I seemed to start having = dead | notes.

Also, the 4 or 5 windchests that I connected up were done 25 or so years ago so your other responders are far more experienced, I think.. However when we encounter problems in my lab like you describe [spurious signals or responses when a switch is actuated] one of the first things we look for is 'ground loops'. I assume that what you're calling 'neutral' is what I call the 'ground' or 'common' or 'local ground' return to the low voltage DC supply. Make sure that there's only one return lead from each chest & that no wires are touching or shorted. You might try disconnecting the common [return] lead from the chest & see if any notes can be made to sound. If they do, you've got another return path somewhere & you'll probably have to root around with an ohmmeter to find it.   Good luck!   Gene

But as Richard points out - some of us that are organbuilders sometimes are way too busy working to spend much time answering questions. And some of us don't always have the knowledge to answer your inquiries.   Even though i am an organbuilder, electrical stuff is kind of out of my realm so I hesitate to answer your questions. Someone like Richard, who is also an electrician, is a better person to answer the current questions you have. Not everyone is versed in every since aspect of organbuilding.   Also, and this isn't just for you but for everyone on the list asking questions, TRY to give the most complete information you have concerning the problem(s) you are facing. It makes it much easier for the rest of us to answer your questions.   Off to work!   David -- ********************************************************* David Scribner, Owner DIYAPASON-L - a mailing list for the owners/builders of their own home pipe organ mailto:owner-DIYAPASON@pipechat.org

Then simply multiply for the max. amount of current needed.   My guess is at an average of 100 ohm/magnet - could be more or less depending on type or brand - drawing .120 amp a piece times 158 =3D just shy of 20 amperes. Any rectifier 20 amps or more should work fine IMHO.   John V  
(back) Subject: Resistor Diodes From: "Larry Chace" <RLC1@etnainstruments.com> Date: Fri, 14 Feb 2003 09:14:15 -0500   Somewhere out in the barn is a pile of old (and rusty) Reisner 601 chest magnets with resistors soldered across their terminals, no doubt an early attempt to squelch the inductive kickback. The smaller the value of the resistor, the better the squelching, but that also increases the amount of current. (At the limits, an infinite resistor draws no extra current but also provides no path at all for the kickback. A zero resistor provides = an excellent path but of course also shorts out the magnet at all times! [It is always good and helpful to think about the extreme conditions -- that will often tell you a lot about the in-between conditions!])   Daniel's description certainly sounds like the magnets are fitted with diodes and that they were connected with reversed polarity in the added offset chest. A simple (perhaps *too* simple) debugging tool is a 12v light bulb (automotive brake light, for example). Connect it in series with the rectifier and provide a hefty switch to bypass the lamp for = normal operations. For debugging, when you suspect there might be a possibility of a short (!!!), open the switch to place the lamp in series with the = rest of the circuitry. If there is a short, the lamp will (probably/possibly/maybe) light up, even dimly. That is your warning that all isn't well! (This approach can also be done, perhaps more = practically, as part of a small test rig on your workbench. Use the series light bulb to check out magnets for proper operation. In case of a shorted magnet = (or reversed diode), the lamp will light but there won't be a dead short = across the power supply.   Resistor or diode??? How many marking bands are there on the component (after scraping off any accumulation of dirt and grunge)? If there is = just one white band (near an end), then it is a diode and that end is the cathode ("bar") end, which needs to point towards the positive side of the power supply (in order to be a non-short!). If there is just one *black* bar, then this is a zero-ohm resistor (yes, they make them), and someone has wired a short across your magnet! If there are three or four, in living color, then you have a resistor. (If there are five, then you have a 1% precision resistor, highly unlikely in this case!).   Radio-Shack has (or at least *used* to have) a series of little = "Engineer's Mini-Notebook" pamphlets that can provide some basic and useful information, in case you don't have a more comprehensive textbook at hand.   Happy debugging!   Larry Chace      
(back) Subject: Re: Wireless hook-ups?? From: "Larry Chace" <RLC1@etnainstruments.com> Date: Fri, 14 Feb 2003 09:25:58 -0500   My comments yesterday regarding wireless were not meant to suggest that it is an inappropriate application of technology to pipe organs, and I apologize if that is how it seemed! (No, no one has complained!)   The intent was simply to say that whether or not something is appropriate (in terms of cost, longenvity, artistry, or whatever) is often a matter of the context (the "big picture", as it were).   I, too, use wireless Ethernet at home (Mac iBook), and it is a liberating technology, but it is also not without its costs. A wireless connection system for a pipe organ will have to transmit enough data often enough to make sure that the instrument's response is as good as a hard-wired connection. I would expect that the systems from Peterson and others have solved the problems of error recovery, interference from other wireless devices, and so on. I'd rather not have to solve those problems myself! ;-)   Larry Chace

This has me puzzled. What's a 'direct electric Mechanical windchest'? Sounds to me sorta like a Wicks type conversion of a tracker.   And then there are those 'resistor diodes', - another confusion point. I'd think they are most likely just plain diodes. If the recently added chest happened to be hooked up with the polarity reversed, it could put one awful big honkin' load on the power supply as well as causing possible diode failures.   Another point, if I'm not getting messages crossed in my mind; several people have mentioned checking the load on several magnets with a multi-meter to calculate the load on the power supply. But what about just sticking a volt meter on the 12 v line some place, watch the meter and then plunk down a big chord with all the stops engaged? If the voltage drops appreciably, it seems there might well be a problem. Check the voltage at the power supply, at the console and at the wind chests. If there's a wiring problem the voltage would vary considerably based on the location. If the problem is with the power supply itself, the voltage will drop right there when under a big load.   When I start having problems with something that worked yesterday, what I usually do is review what I've changed today. It usually doesn't take too long to discover my mistakes. This makes a pretty good case for recording all my changes as I proceed.   Just my incoherent thoughts.   John     danielwh wrote: > . . . . . > Today I ran into a strange problem > Of a direct electric Mechanical windchest, I seemed to start > having dead notes. > . . . . . > What would be causing the resistor diodes to go bad like that > Is there something more serious going on , maybe with the power > source,
