Sk 25
Hi, the pcb layout from my sk24 /sk99 is different as in the assemblyguide. The number for Diode 5 and 9 is 7 and 8. The pcb is marked as 1.2. I did it as in the guide, but it did not work.

Re: Sk 25
The build guide needs to be updated.
The PCB marking and sk25-layout.pdf are correct.
So D5 in the assembly guide is now named D9,
D8 is D7 and D9 is D8.
Anyway, all these diodes are 1N914.
