hello guys amd thanks again for the great community about moogs!
i’m the proud owner of a 1974 minimoog 6447 wich i’m restoring and now is in near perfect working order but remain an huge unique problem to fix:
The OSC 1 and OSC 3 works very good,
they tuned perfectly and make their work, but
if i move the RANGE SWITCH of the OSC 2 it affect the RANGE of the other two oscillators (the OSC 1 and the OSC 3).
This happen with or without the OSC 2 sqitch ON in the mixer section.
the only way to mantain the range of the OSC 1 and the OSC 3 right is to set the OSC 2 range to LO.
in this way the OSC 1 and the 3 works good but the OSC 2 in LO mode is unusable.
Musically speaking if i press A on the keyboard with the two working oscillators ON and i move the OSC 2 RANGE switch from LO i obtain:
OSC 2 in LO range = the other two oscillators at unison in 16’ range works good and maintain the A note.
OSC 2 in 32’ range = the other two oscillators at unison in 16’ range sound the F# note.
OSC 2 in 16’ range = the other two oscillators at unison in 16’ range sound the G# note.
OSC 2 in 8’ range = the other two oscillators at unison in 16’ range sound the E note.
OSC 2 in 4’ range = the other two oscillators at unison in 16’ range sound the C note.
OSC 2 in 2’ range = the other two oscillators at unison in 16’ range works good and maintain the A note as in LO range.
i hope i was as clear as possible
any help to solve this problem?
thanks to all
