I have the Mouser catalog in front of me and if you buy just one 1N4004 it will cost you a nickel. If you buy 250, they'll cost you 2 cents each. They ask to be contacted for the price on more that 500. Even at 2 cents, 1000 are only $20. They have no minimum order and they sell to individuals. Mouser's part number for the 1N4004 is 512-1N4004 They are at 1-800-346-6873 and on the web at http://www.mouser.com   I've bought a lotta stuff from them over the years.   John Bowers     > Hello Drew - I looked up All Electronics and think I found the OSI > diodes - IN 4004 - 1 amp.

Source for all = these small parts was Digi-Key Corporation (Thief River Falls, MN), = 1-800-344-4539. You will fall off your chair at their pennies prices in = comparison to Organ Supply. In the 90s they had a 300 page catalog = which they kept updated and which kept appearing in the mailbox from = time to time.

Analysis: fine grade thin synthetic oil, like sold = in little cans in sewing machine stores. He feels, however, that this = is probably unnecessary with a blower as small as 1/4 or 1/3 HP, as = there is no real weight hanging on the bearings, so that ordinary 3-in-1 = oil will do. The Laukhuff machines have a sort of wick where the oiling = takes place, and they suggest once every ten years. I had a Bobco, too, = and a squirt every year seemed to keep it happy for the decade or so = that I had that organ. So I guess the answer to oiling is "common = sense." Somebody must have some paperwork from Meidinger that tells = what they suggest. Aside: should you happen to cross the path of a = clean .18 HP or .25 HP blower in your travels, I'm looking for one.     All the best. Paul Gunzelmann Gunzelmann Organs, Columbus, OH         Wellspring of great knowledge:   Could someone please tell me what type of oil I should use on my = Meidinger Blower and also how often I should oil it? It's a .25HP = single phase that I bought used about a year ago and was probably made = in the 1970's. It runs silently and smoothly and I want to keep it that = way which is why I need the information above.   Also, does anyone know of the cheapest source for diodes? I need 5 = unified ranks worth and have bought them from OSI in the past but didn't = know if they're the cheapest or not. I wanted to take time to say = thanks to everyone who's helped me with my technical questions in the = past.

(back) Subject: Progress? From: "Robert W. Taylor" <rtaylor@socket.net> Date: Sun, 8 Feb 2004 09:34:59 -0600   It seems like some things happen in a hurry. A burst of progress, = followed by a bigger burst of problems. I responded to some on this list recently, stating that I was almost ready to put wind on my great/choir duplexed chest. After a three week delay, that has finally happened.   The delay was occasioned by my bringing in two EE students to assault all the old wiring. Specifically, the relay and ladder switches. These guys know nothing about organs, but are anxious to learn. The trouble is they can take things apart too fast. I am left scrambling to keep them on course while at the same time recording the existing wiring flow. Another support task I must perform, is teaching these young lads how to solder when the subject wires are not on a circuit board.   Anyway, I finally finished modifying the reservoir opening from an oval so that I can attach a round 8 inch line. Then I made some last minute measurements, and put a hole in the floor for the 8 inch PVC elbow. = Within an hour, the chest which had not been pressurized in five years. felt the kick of the 2 hp blower. Or course the sound was deafening as unseated valves and access holes roared.   The interesting problem that surfaced was the connection to the 49 note harp, which has been patiently waiting for wind for two years. My = drawings of the original installation did not show exactly how this harp was = winded. Giving the 50-50 choice, I choose the wrong one and winded the harp from the regulated side of the reservoir. No big deal.   So this next week, I will be working on the great/choir stop action valves which seem to be all miss regulated. That is the only thing on this chest that easy to work on. Originally, Aeolian had installed this 8 rank monster under a staircase. Every trick they had was used to make the = chest compact. The primary valves which would normally be mounted on the side, are literally hanging underneath the bottom boards and connect to the side through an abstract channel board. The toe boards overhang the chest, = and through offset type plumbing, some pipes are in mid air, over-the-end of the chest, which also cleaverly blocks the top access to the stop action. The gross flute gets to share part of the Aeoline toe board---so much for being skinny--the fat neighbors move in. Oh well, in another 1000 hours = or so, this thing will really be good.   Bob Taylor      
(back) Subject: Re: [Residence Organs] Diodes and electronic parts From: "Harry Chase" <wa1vvh@net1plus.com> Date: Sun, 8 Feb 2032 12:37:50 -0500   These diodes are part of a series starting with 1N4001 and going up to - I believe - 1N4007, the numbers go up in order of increasing reverse = voltage rating. The 1N4004 is rated at 400V peak reverse voltage while the = 1N4001 is rated at only 100V. The problem in using lower voltage rated diodes with solenoids is that when the current to the solenoid is turned = off ( as you release a key) there can be a short but *very* high voltage electrical spike produced. (This is what causes most of the RFI to = nearby AM radios!) Your suppression diodes have to be able to handle whatever voltage may be produced by these switching spikes or else they = may gradually --- (or suddenly) go bad.   In general, the 1N4004 ,and up, diodes are fine for this purpose. Avoid the 1N4001, which seems to be the most commonly found! Hope this helps -     Harry Chase   .. .. .. .. ..   ----- Original Message ----- From: S.

At least I've never heard of any problems with their quality.   Incidently, 1N4005 and 1N4006 are all at that same price if you require the higher voltage.   If you choose to pay more, that's fine too.   John     wcjharrisville wrote: > > Hi John, My only question: Is the quality of the 2 cent-a -piece > diodes the same as the higher priced ones? > I am reminded of a writing by John Ruskin - "It is unwise to > pay too much but worse to pay too little - - -" or are they > pretty much the same?

I have eight single rank chests with 61 notes per, so I split the 65 conductor telephone cables from the chests into three groups = of wire at the relay end about a foot from the end of the cable. Then I installed heat shrink tubing on each of the bundles and a DB-25 on the end of each bundle. When I connect them to the relay, I only need to match up plugs #1,2,and 3 to the three connectors on the relay board for that rank. In the case of offsets, percussions or the toy counter, I have one plug = for each 12 note offset, one for the entire toy counter, one for the chimes = and two each for the xylophone and the crysoglott.
