So,

my SDS7 died a few weeks ago.

It has 12 modules and runs very hot. The rectifier for the +5V made a noise
and the display flickered in and out.

I´ve removed all modules and the CPU starts and run with no problem.
Reseating modules one at a time works fine but the more modules that are
connected, the more there is noise on the +5V rail ( no kidd....lol ). The
VCO´s sound garbled and the audio output has hum.

I have replaced the capacitor on the +5V rail but there is still around 1V
AC half wave noise on it. Both before the regulator and after the regulator.
This leads me to believe that I need to replace the rectifier bridge with
one that can output more current.

Does anyone have any suggestion for a suitable one ?
