Hello gentlemen,

after several problems with the built-in
power supply "JRC CBD-1197" and changing
several 'parts' in the past, the powersupply 
now died definitely....

There is absolutly no DC-Voltage on the 
output side (220V AC-input of course,hi).

The problem is, that I can't get a new one of
this power supplies to change it completly here.

As I am not an electrician, I now have
a big problem...

The manual not even shows me a circuit-diagram!

The power failed within a part of a second,
no smoke and absolutly no smell of destroyed
parts. All fuses are ok too. 

I made 100 RTTY contacts this weekend without
problems (NOT driving 150W) and yesterday,
while working C6AKQ on RTTY it leaves me....

Can anyone out there help me - maybe with a
circuit -diagram ? Importing things from US
to Europe is absolutly not affordable now, I
think.

Is it correct, that the power supply gives +60V
to the transeiver - would it be possible to 
use an external version of power supply ???

Maybe somebody has experience with such problems,
but I still hope to detect the failing part in
the CBD-1197.
