Hi Tibi,
Try 1000pF and 2200pF 500V silver Mica on C11 and I like the 2200pF better, the base handling is better.Will start on the the laser mod this weekend. I will use film cap for 1nF and 100nF, cannot use silver micro there since I cannot get the 100V 1000pF, only 500V is available but it is too big for that job.

Thanks

On laser mod a 100nF MKP is my recommendation. Vishay 1837 will perform excellent.
On pin mod it is mandatory to use a 1nF silver-mica.

Psu working, right now i am checking my IC solder points.

Should there be a connection (continuity tester says there is one) between LA6541 Pin 10 and 11?

There is no continuity between pin 10 and 11 on LA6541.
Please check your soldering.

Sure? I checked all my pins, absolutely no soldering bridges on all ICs. But there seems to be a VERY small bridge under the solder mask going from trace 11 to 10. Shall I cut it?

Removed all solder from the pins and liftet them. Still a connection where, according to the schematic there should not have been one. As said before, I checked the PCB and saw a very tiny bridge on the PCB that somehow did not fit Tibis otherwise so perfect routing.

Check below pin 10 and 11 where the solder mask has been scratched. There was the connection that caused pins 10 and 11 to be "connected". It is no longer. Connections now are as the should be according to the schematic. Can I safely power on now Tibi? ;-)

I can confirm that there is no connection between pin 10 and 11.

Engage !
