Mellotron tape change

Melotron can change a sound more if you change a tape rack. This video explains a way of the exchange of the tape rack. 1 : Take off a lid. 2 : Take off a keyboard. The keyboard is fixed with four screws. 3 : Take off a metal plate for tape guides. 4 : Take off tape. The tape is fixed with four screws, too. 5 : Lift a tape rack and take it off. 6 : Put the another tape rack (A chorus, an oboe, the sound of the vibraphone are recorded with this case). 7 : Install each part in a reverse procedure. Will it be easy than you load a sound in memory?
