What model of Baldwin is this organ?

..

Hi, after googling I fond there were some available on ebay. That is your best bet.

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.

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.

Hello endaya try www.digikey.com if you are using a 2amp buss fuse, its available, 117V is applicable to 220V, just follow the amp rating.

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.
