Still that's impressive , heavy duty! 
It's been fun getting to know it for example I was trying to edit the presets for a while thinking why wasn't I able to chnage the decay or attack before I real side how the presets and panel memory worked. Real interesting coming from modern synths , u can see the natural evolution in certain areas.

It was purchased for a very small sum. After that month it had settled to stable state, and then we could start assessing what needed to be done.

The trimmers on these things ate awful. 
It's relatively stable now, but being at a commercial studio it's powered up all the time anyway.

Continuously for a month? as in on all the time? That's a great machine.

I'd be inclined to leave it powered up continuously if you can.

One CS80 that I service took about a month to settle properly once powered.

Stand wise, I'd say one of those heavy duty keyboard/mixer stands. Make sure whatever you use keeps the vents clear.

Thanks guys! All sorted - bought a 500W rated isolation transformer and continuous unit. And she came to life! 

Figured as it is only in a studio a really good transformer would be better than converting it internally.- cheaper also. $150AUS.



This group is a great resource, thanks to those who helped out.


What's the best way to use the cs-80, is it ok to keep it running for 8-9 hours at a time in a well ventilated room , or should I turn it on and off as required. I know it takes a while to warm up etc.. 

Also anyone recommend a good stand for it?
The grills underneath look like they have taken the weight of a stand from the previous owner..
Thanks

I suspect you've taken out the fuse in the stepdown transformer.
CS should be OK.

to be safe you should overate your stepdown transformer, so you've got a nice bit of headroom.

Make sure that it's rating is for continuous, and not peak power.
I'd go for a 250W -300W continuous rating... that's probably going to equate to a peak rating of 500W-750W.

Maybe step down transformer is dead, or some protector inside it. CS80 asked more power then it could supply...

Just check it's output if there's voltage. If yes, you can check fuses in CS, but they are probably OK. 

And never leave electric devices on when walking outside. Especially with unknown machine you switch on for the first time. I'd never do such thing. You never know which problem can appear, maybe even fire. That would be expensive lesson.

Hiya got  a cs-80 from LA shipped by FedEX, arrived plugged it in, it is labelled 117 Volt 180W . I used a step-down converter rated at 75W - i used it for my Memorymoog Plus. The CS_80 worked beautifully, left it on went for a walk came back and it was off. The power switch is on but no light! No sound. Did i blow the fuse? Did i do some serious damage? I'm going to the electrical store first thing tomorrow to buy a high rested converter, will she return to life after my abuse?
