Electronic organs - circuits, experiences and interests

One would not want to forget which trimpot he was twiddling!!!. The adjustment and tuning must take weeks.
Thats a bit scary for me. It is a thing of great beauty though, I must admit.

It is not that bad.
You take a chart of musical notes with frequencies listed and set the first board up with a tuning fork or electronic counter. Then go on to set each board up in the same way as a stringed piano.
Then repeat the process for any harmonics that are analogue if there is any.
Harmonic levels would be to the tuners taste I guess.
Lets hope there is a good heat spreader above the power amp in the bottom of the cabinet so that any heat related drift is even so that only the pitch changes as it warms up.
