How do I fix a Thomas organ that suddenly has all B flat keys, including foot pedal, not working?


get schematic from web search, find tone generator for Bb, look at PCB where connections are for possible cold solder joints or bad tone generator.

Thomas playmate color glo organ series 1200


This is not one of the newest organs around. The organ still could have real switches. Like silver threads touching when a key is pressed. sully some oxidation on these contacts should not be noticed while playing, but if you can reach the contacts, try some Contact cleaner on the contacts like Deoxit in the US and Kontact 60 in Europe.

I purchased a used Hammond Organ Aurora, Model 700, 710 C125 but the previous owner did not have the manual for it. I am looking for a manual so I know how and what to do to play it. I don't know what...


Try the organforum . com. There are a lot of Hammond people there. The model 700 is the base model and probably enough to get you started.
Also just get a organ music book as a lot of the vernacular is in those. Also check your library for organ books. OFTEN the user manuals aren't much use to learn the instrument.

Most organs will either have tabs or drawbars. These select the type of "voice" and often one selects more than one as a mix. Each keyboard is refered to as a "Manual". Most organs have foot pedals. Each of the manuals and the foot pedals will have a seperate set of tabs associated with them.

To get started, turn on the organ and press the expression pedal which controls the volume... experiment setting a few tabs or drawbars an play notes on the manuals. You will soon learn what controls what.

Note that some models of Hammond organs used rotating tone wheels and those require lubrication. Those that do, usually have a power switch labelled "start" and "Run". These organs are usually higher value and one should have them serviced before using.

Re: Wurlitzer Digital Home Organ


If you have it apart, look in the area of where the power cord goes in. It would help me if you could mention the model number of the organ.The capacitors are in the same area as a fuse would be. The capacitors smooth and filter the A.C. power after the power goes into the power transformer and is then converted to D.C. to run the components. A fuse could be in the A.C. line or in the D.C. line depending on what it is designed to protect. With a model number we could do a search for a schematic and have a look at the most likely problem spots. The schematics for older analog organs are getting hard to find for free but a newer digital one may be easier. Let me know how you make out. Here is an interesting article that may give you some clues:http://www.theatreorgans.com/hammond/keng/kenhtml/wurlitzer%20organs%20by%20frank%20pugno.htm Here is another link with info:http://www.combo-organ.com/spares_and_repairs.htm#Electrolytics Let me know if this helps.

I have a Wurlizer Digital Home Organ that suddenly quit working...no sound at all, but when you turn it off, it makes a ''puffing'' sound. (Sounds like bellows aren't working). I cannot find anyone in the...


Hello there:
on the back of the organ if you remove the back of it and look to the left side there will be a set of fuses that control different features of the organ
there is also capacitors that sit further in the organ so you may want to check them out too there is a wiring diagram on the inside of the back cover this will help you determine what size fuse may be needed
There used to be a piano and organ shop that was located in tyler i dont know if they are still there i live here in dangerfield which is located in northeast texas and i have a dealer here but i dont know if they would do you any good being that far away.
I will post a comment tommorow when they are open to see if they can give me a closer dealer for you ok it is called the music connection so you may want to search the internet for this site ok
best regards michael

Looking for a schematic of the Casio ctk-700 to


The keyboard is LIKELY scanned as a matrix.

You have two problems:

The contacts in the Thomas will have to be totally disconnected rendering use of any of the Thomas organ unlikely.

The second problem is that the keyboard LIKELY has velocity sensing. This means TWO contacts must be used PER note. One contact "makes" first and "breaks" last. This is used for velocity sensing on synths. The Thomas foot pedals likely only have a single contact per pedal, and even if they had two, it is unlikely they sequentially close..

The matrix scanning is accomplished by sensing the connection of two crossing points on a matrix of circuit lines. USUALLY each of 12 wires tie to all of one note across the board. Then two other lines for each octave "strobe" the first make contact and then the second of those strobes the second make contact. There are two of these strobe lines for EACH octave on the board.

Remember that these lines scan at digital logic speeds so wire length and NOISE/STAIC DISCHGARGE PROTECTION is a must.
