Hello r/organ! I am just beginning my journey of attempting to fix up a Baldwin Bravura I bought at a thrift shop while in college 15 years ago. I am probably in over my head but the journey to me is worth more than junking a cool piece of history
I started by marking all the keys that aren't working or are only working partially. I opened up the back and began taking a few components apart to clean the 40 years of dust and gunk accumulation. I was able to find the technical manual on eBay in hopes to help for some of the issues but at most it looks like it can provide me assistance with how to take apart certain components because all of the electrical schematics go right over my head. I understand the basic concepts of resistors, capacitors, diodes, ect. But as a whole and how they function together is a bit past my understanding. I am an electrician and took some electronics classes in high school, I can solder decently but most of what I have done so far is just clean and label connections so I can put it back together correctly.
I noticed that A, D, and A sharp keys are non-functional with exception of some of the solo (upper) keyboard keys only under certain instruments. This has been at my parents house for almost a decade and I haven't really touched it but since then a lot of the solo instruments when turned on will play a certain tone of that instrument eternally without any keys being pressed. If I trim the volume way up while that is happening I can still faintly hear response from pressing the keys individually but it is always overpowered by whatever is failing on those instrument selectors.
Another thing is I don't think the reverb is working and that seems to be its own separate component (system).
I'm not necessarily asking for anything but want to greet the community, show my project at its current state, and if any of these issues sound familiar to anyone I would welcome some advice. So far I have purchased contact cleaner, an air nozzle for my air compressor and the Technical manual in hopes to make some progress.
Thanks for looking
