Nice web page Tom.
most LOVELY instruments...
I for sure must spend some more time looking at them all again. & again most likely too... :)
Well my 701 seems to A: not be recording correctly & B: the accomp. section plays NO chords
in any mode (fingrd/auto/arp.) I am blaming this upon damage done either in shipping or made to look such.
701's have big chunky wood as you most likely know, and there was nothing between them and the box.
There was hardly anything in the box to protect the entire unit for that matter.
Well on the arp./chord/accomp side, there ise a big chuck bashed out/ pushed in etc.
I have seen this happen on organs (which I have 7) if they are jarred.
the speaker on the entire other side also became dislodged, hinting @ the impact.
Both fuses are in tact it seems, so I am a bit lost. Also looking up some stuff upon the 701 there are some
mods I'd like to do, and some empty slots I've heard nobody talk about thus far, as I have found.
So I have many questions and inquiries.
I really enjoy cheesy auto chords &; was so stoked to hear these, yet now I am dead in the water.
Sorry for long rant...
I was org. thinking I was just dumb and the 701 didn't work as simple as most ALL other keyboards/organs
(turn chord switch ON) and I'm just doing something wrong, yet I am pretty sure it's malfunctioning.

So it sounds like your 701's issues are due to damage rather than some electrical component failure (of course the damage could have CAUSED electrical component failure...). This might be "relatively" easy to find the cause of. What have you done on it so far? First step for me would be to open it up and check all the circuit boards for physical damage. Look for cracks - could be major breaks or small hairline cracks, just enough to break a trace and stop continuity. I'd look for disconnected or broken wires/ribbon cables between boards also. The Chord switch itself could be a problem too - maybe it was corroded and never did work. You could disconnect and remove it and check it for continuity. Also look for larger components that may have gotten jostled when the thing got smashed - maybe their solder connections were broken loose - try wiggling things and see is the solder pads move.
I'd be willing to try and help you through this - I'm no expert, but I learned a hell of a lot about how my CT-360 functions while modifying it. Do you have a good camera (and know how to use it)? If you could take a bunch of pictures and email them to me, that'd help. I might be able to identify the chord sections of the circuit boards for you.If you can, send me:
1. Overall photos, outside & inside,
2. Close-ups of the damage - outside & inside.
3. Good clear shots of each circuit board, both sides of each board if possible.
Are you good with soldering & de-soldering?
