Hello again folks...I hope everyone is doin' alright...
So it turns out, according to the schematics, that, I'm missing the "KLM-599 Joystick"
board completely. I'm not exactly sure what this board looks like but I have connector 1B
and 8B just hanging loose inside the chassis.
I'm not really interested in replacing the joystick at this point...I doubt I'd use it much
anyway...
Can any of you help me out rigging something up to get the unit so it plays in tune again?
Gordon, you said I could potentially wire up a couple of 4.7K resistors...but it looks like
that board has a few more components, where would I install these resistors exactly given
that I'm missing the entire joystick assembly and board?
Any help you guys could offer me is REALLY appreciated...
Of course, I could just get by practicing my up a fourth, down a fifty, transposition skills
but I'd rather not. (I actually had a guitar teacher once who claimed that he played in a big
band and would intentionally tune his guitar 1 or 2 semitones out just to practice his live
transposition skills and avoid boredom playing the old standards)...jeez...
Oh, here's a thought, is there a course-tune master trimpot somewhere that I could adjust
instead of trying to simulate the joystick board somehow?
Later Y'all,
-Tim
