Subject: CP strange behaviour

From: "atuzzi" <antoniotuzzi@...>

Hello polarized guys,

I'm trying to understand why my CP is acting strange.
At startup, sometimes about 90 % of all leds are on, but is not
possible to change any parameter. Sometimes, after a couple of secs
goes ok.
But when the startup is ok and also after doing the complete reset
(and related adjustmetns), I'm getting strange results from, for
example attack and releases. Or I'm getting unwanted modulations in
the sounds...

I'm suspecting that the DC OK signal sometimes is not up: I'm getting
a maximum DIGITAL DC +4.2 (maximazing the trimmer, 4.01 at minimum
position). I have the second type board (so no trimmer for the DIG OK
signal)

Do you think is the LM350k or is the power coming in that is too low ?
and what would be the correct incoming voltage from the transformer?
Can be the low voltage caused by old lytics caps ?
What could be a substitute for the DAC ?
thank you for your expertize
