[sdiy] Wanted: Boss SE-70 PSU schematic

[Synthusiast]

Hi list,

My Boss SE-70 is working great except for one thing: the LCD backlight is
flickering a lot. My scope revealed a ripple of 0.75 Vtt on top of the 15V
DC backlight supply voltage. Much more than the 1 mVtt ripple I measured at
the backlight supply voltage of my SE-50 and looking at my friend's GX-700
flicker-free display (which is about the same display as used on the SE-70),
there certainly must be something wrong. I guess, that the DIY transformer I
got with it did some harm to the PSU of the SE-70. (If you want a cheap 50
Hz VCO, I'll send the transformer to you ;) If anyone of you have a
schematic of the SE-70, please let me know.

Cheers,
Martijn
