Thanks for advice, I will try that. (Although I always tend to have a slight
fear when opening my instruments / electonic devices that I might acciden
tly broke them..)

The schematics would be superb! if you just can find enough time to make a pdf-copy of it I´d appreciate very much !

glad to hear from you as another 707 owner. Good news: the power switch is commonly available at electronic stores. But I would recommend to examine the original part first and then buy an exact replacement. The best would be to put the 707 on a trolley for a few days. To get to the power switch you have to remove the back cover, top shelf and roll cover and then fold up the front panel and upper manual. Things will not be that complicated as it looks at first, and a lucky 707 will be worth the effort.

I got the original schematics with my 707, so if you should get into any trouble, I may help you out with an electronic copy (which I have not prepared yet).

All the best to Finland,

I have a 707 in my studio too (s/n 1339) which I´ve had for about
6 months now. It is very beautiful thing and it sounds absolutely
gorgeous but there´s one slight problem with it.. the power switch
is broken (totally off its socket) and I have to press the button down
Really Hard so that the contacts let electricity throught.. This is quite
worksome for a pleasure of playing&hearing the organ.

I didn´t get any schematics with the organ (not even inside of it),
thought as I´ve opened the back wall the wires show pretty clearly
where & what wires goes to the power switch but it seems to locate
in quite hard place to be replaced.

Do you have any instructions on fixing the problem?

My other 2 organs work nicely; the Eminent 310 Unique and Yamaha
CSY2 (btw the Eminent came with schematic files inside it..)
