C2 looks like 0.1uF. You can see it in the photo at the start of the thread and post #81. A cap like that wouldn't be 1uF AFAIK. The drawings on drachenforum agree.
There's no such thing as a 710k resistor. The standard series have been around since long before that sewing machine was made. Also note it's in series with the gate of some kind of thyristor - it wouldn't be so high. Comparing the schematic on page 7 with the PCB layout on page 1, it looks like whoever drew the schematic made a typo and it's actually 10k.
