Project Blue Tarp: The organ

Some time about 1984 or 85, my parents purchased a Yamaha organ for me to learn music on. Fast forward some decades, and the organ has now spent the last 10 years or so sitting in my garage, much to my shame. Before that, it spent some time sitting in a grain shed on my parents' farm.

I've been keen to get it out again, to get it being used, and also to have it as a project to fix it up. Here it is in it's current home, under the blue tarp of mystery:

• 
• 

The model is a Yamaha Electone A-505. A quick assessment shows that it still makes noise, but will need some minor work.

• The master volume pot is stuffed, and only works in one position - everywhere else is scratch noises
• The expression pedal has lost it's tension and just flops around. Floppy organs are never good
• The drum buttons seem to be a bit stuck. Only about half of them work
• The drum volume is stuffed as well. That one is a dual potentiometer, so not looking forward to finding a replacement for that
• The top keyboard works, but if you put any pressure around the piano/harpsicord switches, the whole top keyboard cuts out
• The bottom keyboard mostly works, but there are a few keys that need to be hammered hard to get a sound
• The 'G' key on the top is a bit wobbly. That's not a new issue...I seem to remember thinking that sticking a 50c piece between the keys would be a good idea when I was about 10 years old. Not sure why. Seemed like a good idea at the time
• There is decades of dust, dirt and spider poo all over the thing. Removing that will probably be the first job

Here it is in it's new home, along with the original organ lesson book from the 80s:
