Step Up Instruments, Part II

(con't from Part I)
It may happen that the novice organist's taste may turn to playing theatre organ arrangements, to where certain voices only available on this type of instrument are needed.
Back in the 1960's the Conn company manufactured a very fine analog theatre organ in the model 640 (photo), which, in addition to self-contained loudspeakers, was equipped with a built-in 2 speed Leslie speaker through which the tibias and vox humana were wired to speak.
This instrument, while it still had a 25-note flat, radiating pedalboard, had 2 full size manuals and 60 watts of power.
Being a vacuum tube oscillator organ like the Rhapsody model [See blog, Step Up Instruments, Part I], it had a full sound that was very solid.
Later models of this instrument were transistor oscillator organs, which sounded more tight and up front.
Both types had their individual merits however, and were very reliable.
The Solo manual was supplied with sub and super couplers which gave full block chords a big, powerful sound.
This was the second step up instrument that one classically trained organist used to continue his journey in organ playing.
