Hi
After several years of problems with faults, York Baptist Church are wanting to replace their existing Wyvern digital organ - and it's available either for repair, or for conversion to Hauptwerk (or other) computer simulator. Some pictures at https://goo.gl/photos/zp1i42GAHZk514S16 Contact me if you're interested, and I'll put you in touch with the relevant person at the church.
Every Blessing
Tony
