Hi,

This is the first MP566 I'm putting together.

I have two questions about some parts.

In the 'parts list' C4 is described as 22uF350v.
However, the (only 22uF) capacitor I received indicates 22uF315v.

R51 indicates 7R5 on the 'parts list', but when measuring I get 8R9.

Can I go ahead and just install both of these?

Thanks in advance!
Tom

No problem, you can move forward.
The 315V is still well above our B+  which is at 225V.
If the colour code on the resistor is correct (violet, green, black, silver) then the resisor is correct within 1%. The typical ohmmeters are generally not very acurate for the extreme values (very small or very large). Also, it adds the resistance of the leads, and connections to the resistor value.

Thank you very much!
Better to be sure :)
