hello list,
thank you all for your help!
i connected everything and seems that all panels power
up correctly.
one of the two distroboards liht up only one of its
leds (the orange led but not the green one. but i
measured the voltages that the board outputs in its
molex connectors and seem correct (12/-12 and zero in
the green cable).
so i connected everything and works fine apart from
the folowing faults i found:
the pitch follower does not trigger correctly . its
trigger seems not in time with the gate signal. the
gate signal is outputed correctly.
aldo also the preamp output is dead.
also, one of my 5 prepamp modules in another panel has
a problem: its envelope output and gate output are
always in full voltage.
but both these probelms are not reall important for
what;simportanmt is this: the frequency shifter module
doesa not work becasue it seems that the carrier
oscillator does not work. from the frequency shifter
output i get the input wave but unvchanged. also from
the carriro vco outs i get nothing b ut a click when i
firtly connect the cable and then nothing.
so it seems that the internal osc of the frequency
shifter module does not work.
could anyone help me fix this?
F/S schemos or ideas as to what my tech should look for/replace in the 
faulty F/S module?

many thanks in advance,
best regards,      :-)
