Hello, my name is***** to Justanswer! Give me just a few minutes to look up some specifics, I'm working on this now.
For organs, you will need an in-home technician. Tell me your zip code, and I'll see if there are any techs in your area.
It looks like you lucked out, there is an organ service company 40 miles from you in Royal Oak. Give them a call, see if they are still servicing organs. These guys are hard to find, and are few and far between.
All County Organ Service
1026 East*****br />Royal Oak, MI 48067
If they cannot help you, let me know and I'll find the next nearest organ tech.
