Minimoog D original

Hi guys
I own an old Minimoog d serial is 12xxx, trying tune the oscillators. Does anyone knows if range is 8 foot what should the frequency be on low A 55 Hz or 110 Hz ?

Thanks

What do you mean by “Low A”? If it is the lowest A on the Mini keyboard, with the 8’ register, I believe that the “Middle-C” on the Keyboard corresponds to true Middle C so the A that is lowest on the Mini keyboard would be 2 octaves below A440 which would be A110. It’s been a while since I had Mini but 55Hz is pretty low frequency and 8’ is a moderately high register, so if I am incorrect, the answer may actually be 220Hz as opposed to 55Hz.
