Hi Lucas,
Maybe you could post some closeup photos of the new board on the web
somewhere we can see them. That way we can see if there is any obvious
problem. No, the vias do not need to be filled.
Which capacitor did you use for C23, the 10p or the 22p? You may have a
clock stability problem and should probably try both.
Most functions should work reasonably well even before calibration so I
would check proper component placement and make sure all pins are soldered.

Hi everybody !
First of all, I would like to thank's Jed and all the team for the good job
done !
I purchased the clone PCB some month ago and I assembled the board these
last weeks. I try it but, unfortunely, the P6 has some probs :
1) At the start, the MG LED blink slowly and goes faster until to stay up.
2) The programmer knobs don't respond.
3) I try to calibrate the P6, but without the 56k resistor plug on the power
supply board, the LED 5 and 8 are alight.
4) In test mode, the programmer knobs respond
5) I think, there is no sound change when I play with the different knobs
(sorry I'm just an electronician guitarist who like to fix up some hold
stuff =) )
My differents readings of these group let me think that the problems 2 and 3
come from the DAC08. Regarding the MG LED, I don't really know because I
fixed the 2 bugs on the PCB board.
So before trying to fix all these issues, I've just some questions :
- Is it really necessary to fill the metallized vias ?
- Is there a procedure to check the good functions of the board with the
different test points ?
Thank's a lot for the help
Lucas
