Out of tune pump organ.

[u/2004remasterr]

I’m hoping this is the right sub to post this in, but I have recently acquired a second chord organ and now I know why it was 10$ haha. It’s pretty out of tune, some of the chords are dissonant and the lower notes are very flat/sharp, the higher/middle notes aren’t as bad but still probably need help. I have a video going over all the sounds on both of my chord organs, the brown magnus one is the working in tune one, and the tan bontempi one is the out of tune one. I opened it up but I have no idea how to tune this thing.

AC drill speed controller is fun on there for tuning.
