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
