SOPP681: I plan to buy a used electronic organ

Secrets of Organ Playing Podcast

This question was sent by Dimi, and he writes about his dreams and the challenges that he is facing. So:
“1. I dream to play at my future organ romantic and baroque pieces, but not only that.
2. I plan to buy a used electronic organ (Ahlborn DS series, 2 manual+pedal) and I haven't found the owner manual and the service manual online, I looked on some forums and sent emails to Ahlborn website, but so far no answer.
The price is €250.
I can (barely) afford it, it is about 39% of my total net income, despite that I am optimistic.
I will use my Edirol FA-66 interface and GrandOrgue to test it.”
